Titanium aluminium alloy ke sepheo sa alloy sputtering bakeng sa deposition vacuum. Lipheo tsa Titanium aluminium alloy tse nang le litšobotsi tse fapaneng li ka fumanoa ka ho lokisa litaba tsa titanium le aluminium ka alloy ena. Titanium aluminium intermetallic metsoako ke lisebelisoa tse thata le tse brittle tse nang le khanyetso e ntle ea ho apara. Li koahetsoe ka lera la titanium aluminium intermetallic metsoako holim'a lisebelisoa tse tloaelehileng tsa ho itšeha, tse ka khonang ho lelefatsa bophelo ba lisebelisoa tsa lisebelisoa. Haeba sputtering e etsoa ka nitrogen discharge arc ho qala, ho ka fumanoa ho thatafalloa ho phahameng le ho fokotseha ho fokolang sefahleho sa sefahleho, se loketseng ka ho khetheha bakeng sa ho roala holim'a lisebelisoa tse sa tšoaneng, hlobo le likarolo tse ling tse tlokotsing. Ka hona, e na le tebello e ntle ea ts'ebeliso indastering ea machining.
Ho lokisoa ha liphofu tsa titanium aluminium alloy ho batla ho le thata. Ho ea ka setšoantšo sa karolo ea titanium aluminium alloy, metsoako e fapaneng ea intermetallic e ka thehoa pakeng tsa titanium le aluminium, e lebisang ho sebetsaneng le brittleness ka titanium aluminium alloy. Haholo-holo ha aluminium e ka har'a motsoako e feta 50% (karolelano ea athomo), khanyetso ea oxidation ea alloy e fokotseha ka tšohanyetso mme oxidation e matla. Ka nako e ts'oanang, katoloso ea exothermic nakong ea ts'ebetso ea alloying e ka hlahisa li-bubble habonolo, li-shrinkage pores, le porosity, e leng se bakang porosity e phahameng ea alloy le ho se khone ho fihlela litlhoko tsa letsoalo la thepa e shebiloeng. Ho na le mekhoa e 'meli ea mantlha ea ho lokisa li-alloys tsa titanium aluminium:
1. Mokhoa o matla oa ho futhumatsa hona joale
Mokhoa ona o sebelisa sesebelisoa se ka fumanang matla a phahameng a hona joale, se futhumatsang phofo ea titanium le phofo ea aluminium, e sebelisa khatello, 'me e etsa hore aluminium le titanium li sebetse ho theha lipakane tsa titanium aluminium alloy. Boima ba sehlahisoa sa sepheo sa titanium aluminium alloy se lokisitsoeng ke mokhoa ona ke> 99%, 'me boholo ba lijo-thollo ke ≤ 100 μ m. Bohloeki>99%. Mefuta e fapaneng ea lihlahisoa tsa titanium aluminium alloy target material ke: litaba tsa titanium tsa 5% ho isa ho 75% (karolelano ea athomo), 'me tse ling kaofela ke litaba tsa aluminium. Mokhoa ona o na le litšenyehelo tse tlaase le lihlahisoa tse phahameng tsa lihlahisoa, 'me o ka finyella ka botlalo litlhoko tsa tlhahiso e kholo ea indasteri.
2, mokhoa o chesang oa ho hatisa isostatic
Mokhoa ona o kopanya phofo ea titanium le phofo ea aluminium, ebe o kenya phofo, o hatelloa ke isostatic pre pressing, degassing process, ebe o chesa isostatic pressing forming. Qetellong, sintering le ts'ebetso li etsoa ho fumana sepheo sa titanium aluminium alloy. Sepheo sa titanium aluminium alloy se lokiselitsoeng ke mokhoa ona se na le litšobotsi tsa ho teteana ho phahameng, ha ho na li-pores, ha ho na porosity le karohano, ho hlophisoa ho tšoanang, le lijo-thollo tse ntle. Mokhoa oa ho hatella oa isostatic o chesang hajoale ke mokhoa o ka sehloohong oa ho lokisa liphofu tsa titanium aluminium alloy sputtering tse hlokoang ke indasteri ea ho roala.
