Izigxobo zokuxhuma okusheshayo ezakhiwe ngensimbi (forged fluid quick couplings) ziyizingxenye ezibalulekile cishe kuzo zonke izinhlelo zokudlulisa uketshezi ezimbonini, zisebenza njengendawo yokuxhuma ethembekile phakathi kwamapayipi, amapayipi amakhulu, nemishini emikhakheni efana nezolimo, ukucutshungulwa kwamakhemikhali, ukucisha umlilo, nokukhiqiza ukudla. Lezi zigxobo kumele zikwazi ukumelana nengcindezi enkulu, izinto ezinamandla ezilimazayo, ukudlidliza, kanye nemijikelezo ephindaphindiwe yokuxhuma nokukhumula ngaphandle kokuvuza noma ukuphuka, okubeka izidingo ezingavamile entweni eluhlaza okwenziwa ngayo. Inqubo yokufinyela (forging) ngokwayo inikeza ukwakheka okuhle kwezinsimbi, kodwa ukwelashwa ngokushisa okulandelayo yikho okuvula amandla aphelele e-alloy futhi kunqume ukuthi ingxenye yokugcina izosebenza ngokuthembekile noma ihluleke ngaphambi kwesikhathi. Phakathi kwezindlela ezahlukene zokwelashwa ngokushisa ezikhona, i-T6 temper ibhekwa njengezinga legolide lama-aluminium alloys asetshenziswa ezigxobeni zokuxhuma okusheshayo ezisebenza kahle kakhulu, okuhlanganisa nezigxobo ezidumile ze-Camlock, izigxobo ze-Storz, nezigxobo ze-Guillemin ezitholakala emikhakheni yezimboni emhlabeni wonke. Lesi sihloko sinikeza umhlahlandlela obanzi, onesinyathelo ngesinyathelo wokusebenza kwe-T6 heat treatment ezigxobeni zokuxhuma okusheshayo ezakhiwe ngensimbi, sichaza zonke izigaba kusukela ekulungiseleleni kuya ekuhloleni, futhi sinikeze imininingwane yokuthi umkhiqizi ochwepheshile afana ne-Varicpand International uwenza kanjani lo msebenzi ukuze akhiqize imikhiqizo ephakeme. Ngokuqonda isayensi nokusebenza okungokoqobo ngemuva kwe-T6 treatment, onjiniyela, ochwepheshe bokuthenga, nabasebenzisi bokugcina bangenza izinqumo ezinolwazi oluthe xaxa mayelana nekhwalithi nokuthembeka kwezingxenye zokuxhuma abazicacisayo.

Ukwelashwa nge-T6 akukona nje ukuthuthukiswa okungagqamile kodwa kuyinqubo ebalulekile yensimbi eguqula i-aluminium alloy ethambile, esebenzisekayo ibe yingxenye enamandla aphezulu, ezinze ngobukhulu obuqondile ekwazi ukubhekana nezimo zokusebenza ezinzima. Ngaphandle kokwelashwa okufanele ngokushisa, ama-aluminium couplings akhandiwe angaba ngaphandle kwamandla okudonsa, amandla okukhiqiza, nobulukhuni obudingekayo ukuze kugcinwe uphawu oluphephile ngaphansi kwengcindezi ephezulu, okuholela ekuguqukeni, ukuvuza, nokwehluleka okubulalayo kokuxhumana okubeka engcupheni abasebenzi nemishini. I-T6 temper ithuthukisa kakhulu izakhiwo zemishini zama-aluminium alloys afana ne-6061, 6063, ne-2618, okuyiwona avame ukucaciselwa ama-industrial couplings ngoba anikeza ibhalansi enhle yamandla, ukumelana nokugqwala, nokusebenza kahle kwemishini ngemva kokwelashwa. Ngaphezu kwalokho, ukwelashwa kwe-T6 kuthuthukisa ukumelana kwento nokuqhekeka kwe-stress corrosion kanye nokukhathala, izindlela ezimbili zokwehluleka eziyingozi kakhulu ezinhlelweni zokuphatha uketshezi lapho izingxenye zingaphansi kwemithwalo yengcindezi ejikelezayo nezimo zemvelo ezinzima. Kuma-forged fluid quick couplings, ukwelashwa kusiza nasekukhululeni izingcindezi zangaphakathi ezethulwa ngesikhathi sokukhandwa, kunciphisa ubungozi bokuguquka futhi kuqinisekise ukuthi izindawo ezibalulekile zokuvala zihlala zingaphakathi kwamazinga aqinile wobukhulu ngemva kokwenziwa kwemishini. Umphumela ukuthi i-coupling iletha ukusebenza okungaguquki, impilo yesevisi ende, nomkhawulo wokuphepha onokwethenjelwa onjiniyela abawudingayo lapho bedizayina izinhlelo ezibalulekile zokudlulisa uketshezi.

Igama lokukhonjwa kwe-T6 libhekisela enqubweni ethile enezigaba ezintathu zokwelashwa ngokushisa esetshenziswa kuma-aluminium alloys, ehlanganisa ukwelashwa ngesisombululo, ukucishwa, nokuguga okwenziwa ngamandla, lapho isigaba ngasinye sidlala indima ehlukile nengenakugwenywa ekuthuthukisweni kwezakhiwo zokugcina zento. Ngesikhathi sokwelashwa ngesisombululo, izingxenye ezikhohlisiwe zishiswa zifinyelele ekushiseni okuphezulu, ngokuvamile phakathi kuka-515°C no-550°C kuye ngohlobo lwe-alloy, bese zigcinwa kulelo zinga lokushisa isikhathi esanele ukuze kuncibilike izakhi eziyingxubevange ezifana nethusi, i-magnesium, ne-silicon zibe yisisombululo esiqinile ngaphakathi kwe-aluminium matrix. Ukucishwa bese kupholisa ngokushesha izingxenye, ngokuvamile emanzini noma ku-polymer quenchant, okufriza isisombululo esiqinile esine-supersaturated endaweni yaso futhi kuvimbele izakhi eziyingxubevange ukuthi zingaphumi ngaphambi kwesikhathi, ngaleyo ndlela kudale isimo se-metastable esibalulekile ekuqiniseni okulandelayo. Isigaba sokugcina, ukuguga okwenziwa ngamandla, kuhilela ukushisisa kabusha izingxenye ezicishiwe zifinyelele ekushiseni okumaphakathi, ngokuvamile phakathi kuka-160°C no-190°C, bese zigcinwa amahora amaningana ukuze kuvunyelwe ukukhishwa okulawulwayo kwezinhlayiya ze-intermetallic ezinhle, ezisatshalaliswa ngokufanayo, ezikhulisa kakhulu amandla nokuqina kwe-alloy. Ukulawulwa okunembile kwesikhathi nezinga lokushisa esigabeni ngasinye yilokho okuhlukanisa ukwelashwa kwe-T6 okwenziwe kahle kusuka kokungafanele, futhi kuthinta ngqo amandla okudonsa, amandla okukhiqiza, nokunwebeka kwe-fluid quick coupling ekhohlisiwe eqediwe. Ukuqonda lesi sisekelo se-metallurgical kubalulekile ngaphambi kokuhlola izinyathelo ezinemininingwane zokusebenza, ngoba isinyathelo ngasinye kumele senziwe ngokunemba ukuze kutholakale izakhiwo zemishini ezicaciswe amazinga obunjiniyela nezidingo zamakhasimende.

Isinyathelo sokuqala kunoma yimuphi umsebenzi ophumelelayo wokwelashwa kokushisa kwe-T6 ukulungiselela okuphelele nokuhlanzwa kwezingxenye ze-coupling ezifakiwe, ngoba ukungcola okungaphezulu kungaphazamisa kakhulu ikhwalithi yomkhiqizo wokugcina ngezindlela eziningi. Okusalayo kokugcoba kwe-forging, uketshezi lokusika, amafutha, amafutha okugcoba, nokungcola okushiywe phezu kwezingxenye kungadala ukushintsha kombala endaweni ethile, kuvimbele ukushisa okufanayo, futhi kuholele nasekukhubazekeni kwe-metallurgical ngesikhathi sokwelashwa kwe-solution treatment. Lokhu kungcola nakho kungasabela ne-alloy emazingeni okushisa aphezulu, kukhiqize i-oxidation engaphezulu noma ukuhlasela kwe-intergranular okunciphisa ukumelana nokugqwala nokuqina kwemishini ye-coupling eqediwe. Ngakho-ke, izingxenye zivame ukuhlanzwa kusetshenziswa ama-degreasing solvents afanele, izixazululo zokuhlanza ezine-alkaline, noma imishini yokuhlanza yamanzi yezimboni, bese kulandela ukugezwa okuphelele ukuze kususwe noma yimaphi amakhemikhali asele angaphazamisa inqubo yokwelashwa kokushisa. Ngemva kokuhlanzwa, kuyinkambiso futhi ukuqinisekisa ukuthi izingxenye zomile ngokuphelele ngaphambi kokuzilayisha esithandweni somlilo, ngoba umswakama osele ungabangela ukuthi umhwamuko wamanzi usabele nensimbi eshisayo futhi wethule i-hydrogen porosity ebuthakathaka impahla. Ukwengeza, izingxenye ziyahlolwa kulesi sigaba ukuze kuqinisekiswe ukuthi zifakiwe kahle, azinazo iziphazamiso ezibonakalayo ezifana nemifantu noma ama-laps, futhi zimakwe kahle noma zilandelwe ukuze irekhodi lokwelashwa kokushisa ligcinwe kuyo yonke inqubo. Isinyathelo sokulungiselela esihleliwe sakha isisekelo sokwelashwa okungaguquki, okuphindaphindekayo okukhiqiza ama-fluid quick couplings afakiwe anezakhiwo ezifanayo kuyo yonke ibatch yokukhiqiza.

Ukwelashwa kwesisombululo yisigaba sokuqala sokushisa esiphezulu somjikelezo we-T6, futhi sidinga ukulawulwa okunembile kokubili izinga lokushisa kanye nezinga lokushisa lokucwiliswa ukuze kuqinisekiswe ukuncibilika okuphelele kwezakhi ezingxube kuwo wonke umkhawulo wengxenye. Izingxenye zokuxhuma ezikhohlisiwe zilayishwa esithandweni somlilo, ngokuvamile umoya ojikelezayo noma isithando sikasawoti, futhi zishiswe zifinyelele ezingeni lokushisa lokwelashwa kwesisombululo elishiwo, okuthi emazingeni amaningi e-aluminium yezinga le-aerospace libe phakathi kuka-515°C no-550°C. Izinga lokushisa kufanele lilawulwe ngokucophelela ukuze kugwenywe ukushaqeka kokushisa nokuqinisekisa ukuthi ngisho nezingxenye eziwugqinsi kakhulu zokuxhuma zifinyelela ezingeni lokushisa elihlosiwe ngokufanayo, kuvinjelwe ukuncibilika okungaphelele kwezinye izindawo kuyilapho kugwenywa ukuncibilika kokuqala noma ukukhula kwezinhlamvu kwezinye. Lapho izingxenye sezifinyelele ezingeni lokushisa lokwelashwa kwesisombululo, zibanjwa noma zicwiliswa kulelo zinga lokushisa isikhathi esinqunywa ubukhulu bengxenye nokwakheka kwengxube, ngokuvamile kusukela ehoreni elilodwa kuya kwamane, ukuze kuvunyelwe ukufana okuphelele kwezakhi ezingxube. Ukufana kwezinga lokushisa esithandweni somlilo kubalulekile kulesi sigaba, futhi izithando zomlilo zesimanje zihlonyiswe ngama-thermocouple amaningi kanye nezilawuli ezilinganisiwe ukuze kugcinwe izinga lokushisa ngaphakathi kokubekezeleka okuqinile kuyo yonke indawo yokusebenza. Ukuqapha njalo ngesikhathi sokucwilisa kubalulekile ngoba ngisho nokuchezuka okuncane kwezinga lokushisa kungaholela ekuncibilikeni okungaphelele, okubonakala njengamandla anciphile nokuqina komkhiqizo wokugcina, noma ngokuphambene, ukushisa ngokweqile okubangela umonakalo ongalungiseki ekwakhekeni kwesakhi sensimbi. Ukwelashwa kwesisombululo okwenziwe kahle kubeka isiteji somsebenzi wokucisha ngokushesha olandelayo futhi ekugcineni kunquma ukuthi ukuxhuma kuzofinyelela yini ukusebenza kwemishini okucacisiwe.

Ukucisha yisona sinyathelo esibaluleke kakhulu futhi esizwela isikhathi kakhulu kuyo yonke inqubo ye-T6, ngoba izingxenye kufanele zihanjiswe zisuke esithandweni sokwelapha nge-solution ziyiswe endaweni yokucisha ngokushesha nangokufanayo ukuze kugcinwe i-supersaturated solid solution eyakhiwe ngesikhathi sokushisa. Isikhathi sokudlulisa, esivame ukubizwa ngokuthi isikhathi sokulibaziseka kokucisha, silawulwa ngokuqinile futhi ngokuvamile akumele sidlule imizuzwana embalwa kuma-alloys anamandla aphezulu, ngoba noma yikuphi ukuchayeka isikhathi eside emazingeni okushisa aphakathi kuvumela ukuthi kwenzeke i-precipitation engafunwa futhi kunciphise amandla okugcina e-coupling. Izinto ezivame kakhulu zokucisha ezisetshenziselwa izingxenye ze-aluminium coupling amanzi, anikeza izinga lokucisha elisheshayo kakhulu, kanye nezixazululo ze-water-polymer, ezinikeza iphrofayili yokupholisa efanayo futhi elawulekayo enciphisa ubungozi bokuhlanekezela kanye nokucindezeleka okusele. Izinga lokushisa le-quench bath ligcinwa phakathi kwebanga elishiwo, ngokuvamile phakathi kuka-20°C no-40°C kokucisha ngamanzi noma njengoba kunconyiwe umhlinzeki we-polymer, futhi ibhafu inyakaziswa ngamandla ukuze kuthuthukiswe ukudluliswa kokushisa nokuvinjelwa ukwakheka kwama-vapor blankets angabangela ukupholisa okungalingani. Ngesikhathi sokucisha, izingxenye ezincanyana ezinjenge-sealing grooves kanye ne-locking mechanisms ze-coupling ziphola ngokushesha kakhulu kunezindonga eziwugqinsi, futhi lokhu kupholisa okuhlukile kungangenisa ukucindezeleka okusele okumele kulawulwe ngokucophelela kokuklama inqubo kanye nezinyathelo zakamuva zokukhulula ukucindezeleka. Izinga lokupholisa elitholakala ngesikhathi sokucisha lilawula ngokuqondile izinga le-supersaturation ku-alloy, okulawula amandla aphezulu angathuthukiswa ngesikhathi sokuguga, okwenza lesi sinyathelo sibe yisinqumo esiyinhloko sokuthi ngabe i-forged fluid quick coupling eqediwe izohlangabezana nokucaciswa kwamandla ayo yini. Ngenxa yokubaluleka okukhulu okuhilelekile, imishini yokucisha yakhelwe ukushesha nokwethembeka, ngama-fixtures anciphisa ukuvinjelwa futhi aqinisekisa ukuthi izingxenye zicwiliswa ngokugcwele futhi zibekwe kahle ukuze zipholile ngokufanayo.

Ukuguga, okwaziwa nangokuthi i-precipitation hardening, yisigaba sokugcina sokushisa kwe-T6 treatment, futhi kulokhu kubhakwa okulawulwa ngokucophelela ngezinga lokushisa eliphansi lapho i-alloy ithola khona amandla aphezulu okuthi i-T6 temper ibaluleke ngayo. Ngemva kokuqukethwe (quenching), izingxenye zihanjiswa ngokushesha ziyiswe kuma-aging furnaces, noma zivunyelwe ukuma isikhathi esifushane kuphela ezingeni lokushisa legumbi, ngaphambi kokuba zishiswe ziyiswe ezingeni lokushisa lokuguga elenziwe ngobuciko, okuthi kuma-alloy amaningi libe phakathi kuka-160°C no-190°C. Izingxenye zigcinwa kuleli zinga lokushisa isikhathi esinqunyiwe, ngokuvamile kusukela emahoreni angu-6 kuya kwangu-24 kuye nge-alloy nezimfuneko zokugcina ezifiselekayo, lapho kuleso sikhathi izinhlayiya ezincane kakhulu ze-intermetallic compounds zihlangana ngokufanayo kuwo wonke i-aluminum matrix. Lezi zinto ezihlangene zisebenza njengezithiyo ekunyakazeni kwe-dislocation ngaphakathi kwe-crystal lattice, okuyilokho kanye okunikeza i-alloy egugile amandla ayo anyukile kakhulu e-yield strength, tensile strength, nobulukhuni, kuyilapho imingcele elawulwa ngokucophelela yokuguga nayo igcina ukunwebeka nokuqina okwamukelekile. Ukuguga ngokweqile (over-aging), okubangelwa izinga lokushisa eliphezulu noma isikhathi eside, kubangela ukukhula kwezinhlayiya (coarsening of precipitates) nokulahlekelwa kwamandla okuhambisana nalokho, kuyilapho ukuguga okungaphelele (under-aging) kushiya i-alloy ingafinyeleli amandla ayo aphezulu, ngakho ukulawulwa okuqinile kwezinga lokushisa ku-aging furnace kubaluleke kakhulu. Kuyo yonke inqubo yokuguga, izinga lokushisa le-furnace kumele ligcinwe lifana kuwo wonke umthwalo, futhi kuvamile ukubeka amasampula okuhlola (test coupons) eceleni kwezingxenye zokukhiqiza ukuze kuqinisekiswe izakhiwo zemishini ngemva kokuqedwa kokuguga. Uma kwenziwe ngendlela efanele, isigaba sokuguga siguqula umzimba we-forged coupling ube yingxenye enobulukhuni nokuzinza kobukhulu (dimensional stability) okudingekayo ukuze kugcinwe izindawo zokuvala ezinembile (precision sealing surfaces) iminyaka eminingi yokusebenza ezinhlelweni ezinzima zokudlulisa uketshezi.

Uma sebenziwe ngokugcwele inqubo yokwelashwa ngokushisa kwe-T6, yonke ibatch yama-fluid quick couplings enziwe ngensimbi enziwe ngokushisisa ihlolwa ngokuqinile futhi ihlolwe ukuze kuqinisekiswe ukuthi izakhiwo ezidingekayo zemishini kanye nezici ze-metallurgical zitholakele ngaphambi kokuba izingxenye ziye emsebenzini wokuwumba nokuqeda. Ukuqinisekiswa kwezakhiwo zomzimba ngokuvamile kuhilela ukuhlola ama-test coupons ashiwo ngenhla ngamandla okudonsa (tensile strength), amandla okukhiqiza (yield strength), ukunwebeka (elongation), nobulukhuni (hardness), kusetshenziswa imishini yokuhlola elinganisiwe futhi kulandelwa izindlela zokuhlola ezijwayelekile ezifana ne-ASTM E8 ne-ASTM E10.

Ukucisha kudlala indima ebalulekile ekupholiseni ngokushesha izingxenye ezilungiswe nge-solution treatment ukuze kugcinwe i-supersaturated solid solution eyakhiwa ngesikhathi sokushisisa ekushiseni okuphezulu. Ukupholisa ngokushesha kuvimbela izakhi ze-alloy ukuthi zingahlangani ngaphambi kwesikhathi, okungenani kunganciphisa i-hardenability namandla okugcina wezinto. Isikhathi sokudlulisa ukusuka e-oveni ukuya endaweni yokucisha kufanele sincishiswe, ngokuvamile sibe ngaphansi kwemizuzwana embalwa, ukuze kugwenywe ukuhlanganisa okungalawuleki emazingeni okushisa aphakathi. Izinga lokupholisa elitholakala ngesikhathi sokucisha linquma ngqo amandla aphezulu angathuthukiswa ngesikhathi sokuguga. Ngakho-ke, ukucisha kungukuthatha isinyathelo esibaluleke kakhulu kulo lonke uhlelo lokwelashwa kokushisa kwe-T6 kuma-forged fluid quick couplings.

Isikhathi esiphelele senqubo yokwelashwa kokushisa kwe-T6 yeqoqo lama-couplings siyahlukahluka kuye nge-alloy, ubukhulu bengxenye, kanye nokulayishwa kweziko, kodwa ngokuvamile sisukela emahoreni angaba ngu-12 kuye kwangama-30 esewonke. Ukwelashwa kokuncibilikisa ngokuvamile kudinga amahora angu-1 kuye kwangu-4 okucwiliswa ngemuva kokuthi iziko lifinyelele ezingeni lokushisa. Ukucisha ngokushesha kuwumsebenzi osheshayo kakhulu, ngokuvamile uqedwa ngemizuzu embalwa, kodwa ulandelwa yisigaba sokuguga, okuyisigaba eside kunazo zonke enqubweni. Ukuguga okwenziwayo ngokuvamile kuthatha amahora aphakathi kuka-6 nangu-24 ezingeni lokushisa, futhi lokhu kwandulelwa futhi kulandelwe yimisebenzi yokulayisha, yokuhlanza, nokuhlola. Izimboni eziningi zokukhiqiza zingaqeda umjikelezo ophelele we-T6 weqoqo ngosuku olulodwa lokusebenza kuya kosukwini noluhafu, kuye ngepharamitha ethile ecacisiwe.

Ukuqina ngokuvamile kuqinisekiswa kusetshenziswa izindlela ezijwayelekile zokuhlola ezifana ne-Rockwell hardness test noma i-Brinell hardness test, ezenziwa ngqo ebusweni be-forged coupling noma kuma-test coupons amelekile acutshungulwa ngomthwalo ofanayo. Inani lokuqina linikeza inkomba esheshayo nethembekile yokuthi ukwelashwa ngokushisa kuphumelele yini, njengoba kunokuhlobana okusunguliwe kahle phakathi kokuqina namandla okudonsa (tensile strength) kuma-aluminium alloys. Ama-portable hardness testers avame ukusetshenziswa ukuqinisekisa ukuqina ezingxenyeni zokukhiqiza ngendlela engalimazi. Amanani okuqina akalwayo aqhathaniswa nemikhawulo ecacisiwe yezinto ezisetshenziswayo kanye nesimo sokwelashwa, njenge-6061-T6, ukuqinisekisa ukuthi kuyahambisana. Ukuhlola kwenziwa kuwo wonke umthwalo wokwelashwa ngokushisa, futhi imiphumela iqoshwa emibhalweni ye-batch ukuze kutholakale umkhondo.

Ukwelashwa kwe-T6 ngokushisa kuthuthukisa kakhulu izakhiwo eziningi zemishini, ikakhulukazi amandla okudonsa okugcina, amandla okukhiqiza, kanye nobulukhuni, okukhuphuka kakhulu uma kuqhathaniswa nesimo esenziwe nge-forging noma esithambisiwe. Isibonelo, i-aluminium engu-6061 esimweni se-T6 ifinyelela amandla okudonsa okugcina acishe abe ngu-290 MPa kanye namandla okukhiqiza acishe abe ngu-240 MPa, okuphindwe kabili cishe amanani abonwa esimweni esithambisiwe. Ukwelashwa kuphinde kuthuthukise ukumelana nokukhathala, okubalulekile kuma-couplings achayeka emfuthweni womjikelezo, futhi kuthuthukise ukumelana nokuqhekeka okubangelwa ukugqwala kwengcindezi. Ukunwebeka nokwelula kuncipha kancane uma kuqhathaniswa nesimo esithambisiwe, kodwa kuhlala kusezingeni elamukelekayo ezinhlelweni zokwakha. Ukufinyela okufanayo kwezinhlayiyana eziqinisa kusiza nasekuzinzeni kobukhulu nasekuqineni okuphelele ekusetshenzisweni.

Ukwelashwa ngokushisa kwe-T6 kungasetshenziswa kuma-quick couplings enziwe nge-aluminium alloys ezokwazi ukwelashwa ngokushisa, okuhlanganisa iningi lama-alloys avame ukusetshenziswa kuma-industrial couplings njenge-6061, 6063, 2011, kanye ne-2618. Nokho, ama-couplings akhiwe ngama-alloys angakwazi ukwelashwa ngokushisa, njengamanye ama-aluminium grades e-5000-series, noma ngezinye izinto ezifana nethusi (brass), insimbi engagqwali (stainless steel), noma i-polymer, adinga izinqubo zokwelapha ezahlukile futhi awakwazi ukuzuza ekwelashweni kwe-T6 temper. Isibonelo, ama-brass couplings ngokuvamile aqiniswa ngokusebenzisa ukusebenza ngokubanda (cold working) noma inqubo ehlukile yokuthambisa (annealing), kuyilapho ama-stainless steel couplings engase enziwe i-solution annealing noma i-passivation. Kubalulekile ukuqonda ukucaciswa kwezinto zokwakha kwe-coupling ngaphambi kokucacisa uhlelo lokwelashwa ngokushisa. Abakhiqizi abafana ne-Varicpand ngokuvamile bakhetha ama-heat-treatable alloys ukuze bakwazi ukuthuthukisa izakhiwo zomshini ngokwelashwa kwe-T6.

Ukwelashwa kwe-T6 ngokushisa kwandisa kakhulu impilo yokusebenza kwama-couplings e-aluminium ngokwandisa amandla awo, ukuqina, nokumelana nokukhathala nokuqhekeka kwe-stress corrosion. I-coupling elashwe kahle nge-T6 mancane kakhulu amathuba okuthi ishintshe umumo, iqhekeke, noma ivuze ngaphansi kwengcindezi ephezulu, okunciphisa imvamisa yokulungiswa nokushintshwa. Ukuqina okuthuthukisiwe kwendawo yengaphezulu futhi kunikeza ukumelana okungcono nokugqokwa nokukhuhleka okuvela emijikelezweni ephindwayo yokuxhuma nokunqamula. Ngaphezu kwalokho, ukuzinza kobukhulu obuzuzwa ngokukhululeka kwengcindezi ngesikhathi sokwelashwa ngokushisa kuqinisekisa ukuthi izindawo zokuvala zigcina ubuqotho bazo ngokuhamba kwesikhathi. Ngenxa yalezi zizathu, ama-couplings alashwe nge-T6 ngokuvamile anikeza impilo yokusebenza ende kakhulu futhi ethembekile kunalawo angalashiwe, okwenza abe utshalomali olungcono kakhulu ezinhlelweni ezibalulekile.
