I-alloy ye-aluminiyam ye-Titanium yithagethi ye-alloy sputtering ye-vacuum deposition. Iithagethi ze-Titanium aluminium alloy ezineempawu ezahlukeneyo zinokufumaneka ngokulungelelanisa umxholo we-titanium kunye ne-aluminium kule alloy. I-Titanium aluminium intermetallic compounds zizinto ezilukhuni kunye nezixhobo ezinqabileyo ezinokumelana nokunxiba kakuhle. Zihlanganiswe ngoluhlu lwe-titanium aluminiyam i-intermetallic compounds ebusweni bezixhobo eziqhelekileyo zokusika, ezinokwandisa ngokufanelekileyo ubomi benkonzo yezixhobo. Ukuba i-sputtering iqhutyelwa nge-arc yokukhupha i-nitrogen, ubunzima obuphezulu kunye ne-coefficient ephantsi ye-coefficient ebusweni imaski yobuso inokufumaneka, efanelekile ngokukodwa ukugquma komhlaba wezixhobo ezahlukeneyo, ukubumba kunye nezinye iindawo ezisengozini. Ke ngoko, inethuba elihle lokusebenzisa kwishishini lomatshini.
Ukulungiswa kweethagethi ze-titanium aluminium alloy kunzima. Ngokomzobo wesigaba se-titanium aluminium alloy, iikhompawundi ezahlukeneyo ze-intermetallic zinokuqulunqwa phakathi kwe-titanium kunye ne-aluminium, ekhokelela ekuqhubeni i-brittleness kwi-titanium aluminium alloy. Ngokukodwa xa umxholo we-aluminium kwi-alloy udlula i-50% (umlinganiselo we-atomic), ukuxhathisa kwe-oxidation ye-alloy kuncipha ngokukhawuleza kwaye i-oxidation inzima. Kwangaxeshanye, ukwandiswa kwe-exothermic ngexesha lenkqubo ye-alloying kunokuvelisa ngokulula amaqamza, i-shrinkage pores, kunye ne-porosity, okukhokelela kwi-porosity ephezulu ye-alloy kunye nokungakwazi ukuhlangabezana neemfuno zokuxinana kwezinto ezijoliswe kuzo. Kukho iindlela ezimbini eziphambili zokulungiselela i-titanium aluminium alloys:
1. Indlela yokufudumeza eyomeleleyo yangoku
Le ndlela isebenzisa isixhobo esinokufumana i-high current, etshisa i-titanium powder kunye ne-aluminium powder, ifake uxinzelelo, kwaye ibangela ukuba i-aluminium kunye ne-titanium iphendule ukwenza iithagethi ze-titanium aluminium alloy. Ubuninzi be-titanium aluminiyam imveliso ekujoliswe kuyo elungiselelwe yile ndlela yi>99%, kunye nobukhulu beenkozo ≤ 100 μ m. Ubunyulu>99%. Uluhlu lwe-titanium aluminiyam ekujoliswe kuyo yi-titanium umxholo we-5% ukuya kwi-75% (umlinganiselo we-athomu), kwaye enye i-aluminium content. Le ndlela inexabiso eliphantsi kunye nokuxinana kwemveliso ephezulu, kwaye inokuhlangabezana ngokupheleleyo neemfuno zemveliso yemveliso enkulu.
2, Indlela eshushu ye-isostatic yokucofa i-sintering
Le ndlela ixuba umgubo we-titanium kunye nomgubo we-aluminium, emva koko ulayishe umgubo, ucinezele i-isostatic ebandayo yangaphambili, inkqubo ye-degassing, kwaye emva koko i-isostatic icinezele ukubumba. Ekugqibeleni, i-sintering kunye nokucubungula kuqhutyelwa ukufumana iinjongo ze-titanium aluminium alloy. Ithagethi ye-titanium aluminium alloy elungiselelwe yile ndlela ineempawu zokuxinana okuphezulu, akukho pores, akukho porosity kunye nokwahlula, ukubunjwa okufanayo kunye neengqolowa ezintle. Indlela eshushu ye-isostatic yokucinezela okwangoku yeyona ndlela iphambili yokulungiselela iithagethi ze-titanium aluminium alloy sputtering ezifunwa lishishini lokugquma.
