I-Titanium aluminium alloy iyithagethi ye-alloy sputtering ye-vacuum deposition.Amathagethi e-Titanium aluminium alloy anezici ezihlukile angatholwa ngokulungisa okuqukethwe kwe-titanium ne-aluminium kule alloy.Izinhlanganisela ze-Titanium aluminium intermetallic ziyizinto eziqinile futhi eziphukayo ezinokumelana okuhle nokugqokwa.Zihlanganiswe nongqimba lwe-titanium aluminium intermetallic compounds phezu kwamathuluzi ajwayelekile okusika, anganweba ngempumelelo impilo yesevisi yamathuluzi.Uma i-sputtering yenziwa nge-arc yokukhipha i-nitrogen, kungase kutholakale ubulukhuni obuphezulu kanye ne-coefficient ephansi ye-coefficient ebusweni imaski yobuso, efaneleka ngokukhethekile ukumbozwa kwamathuluzi ahlukahlukene, isikhunta nezinye izingxenye ezisengozini.Ngakho-ke, inethuba elihle lokufaka isicelo embonini yemishini.
Ukulungiswa kwethagethi ye-titanium aluminium alloy kunzima kakhulu.Ngokomdwebo wesigaba se-titanium aluminium alloy, izinhlanganisela ezihlukahlukene ze-intermetallic zingakhiwa phakathi kwe-titanium ne-aluminium, okuholela ekucubungulweni kokuqina kwe-titanium aluminium alloy.Ikakhulukazi lapho okuqukethwe kwe-aluminium ku-alloy kudlula ama-50% (isilinganiso se-athomu), ukumelana ne-oxidation ye-alloy kwehla ngokuzumayo futhi i-oxidation inzima.Ngesikhathi esifanayo, ukunwetshwa kwe-exothermic phakathi nenqubo ye-alloying kungenza kalula amabhamuza, izimbotshana ezinciphayo, kanye ne-porosity, okuholela ekuqineni okuphezulu kwe-alloy kanye nokungakwazi ukuhlangabezana nezidingo zokuminyana kwezinto ezihlosiwe.Kunezindlela ezimbili eziyinhloko zokwenza i-titanium aluminium alloys:
1. Indlela yokushisa yamanje enamandla
Le ndlela isebenzisa idivayisi engathola amandla aphezulu, okushisa i-titanium powder kanye nempushana ye-aluminium, ifake ukucindezela, futhi ibangele i-aluminium ne-titanium zisabele ukuze zenze imigomo ye-titanium aluminium alloy.Ukuminyana komkhiqizo ohlosiwe we-titanium aluminium alloy olungiselelwe ngale ndlela ngu>99%, kanti usayizi wokusanhlamvu ≤ 100 μ m.Ubumsulwa>99%.Uhla lokuqanjwa kwe-titanium aluminium alloy target material: okuqukethwe kwe-titanium kusuka ku-5% kuya ku-75% (isilinganiso se-athomu), kanti okunye okuqukethwe kwe-aluminium.Le ndlela inezindleko eziphansi kanye nokuminyana kwemikhiqizo ephezulu, futhi ingahlangabezana ngokugcwele nezidingo zokukhiqizwa kwezimboni ezinkulu.
2. Indlela yokucindezela ye-isostatic eshisayo
Le ndlela ihlanganisa impushana ye-titanium ne-aluminium powder, bese ilayisha impushana, icindezela i-isostatic ebandayo yangaphambi kokucindezela, inqubo yokukhipha umoya, bese kuba ukwakhiwa kokucindezela kwe-isostatic okushisayo.Ekugcineni, i-sintering kanye nokucubungula kwenziwa ukuze kutholwe izinhloso ze-titanium aluminium alloy.Ithagethi ye-titanium aluminium alloy elungiselelwe yile ndlela inezici zokuminyana okuphezulu, azikho izimbotshana, azikho i-porosity nokuhlukaniswa, ukwakheka okufanayo, kanye nezinhlamvu ezinhle.Indlela yokucindezela ye-isostatic eshisayo njengamanje iyindlela eyinhloko yokulungiselela imigomo ye-titanium aluminium alloy sputtering edingwa imboni yokuhlanganisa.
