Kuyini ukubumba komjovo we-Titanium alloy powder?

I-Titanium alloy powder,Izingxenye ze-MIM titaniumekugqokeni okuhlakaniphile, izinto zikagesi ze-3C, izisetshenziswa zezokwelapha nezinye izici zokusetshenziswa komkhiqizo.

I-MIM titanium alloy ngaphambili

Ama-alloys e-Titanium kanye ne-titanium asetshenziswa kakhulu endaweni ye-aerospace namadivayisi wezokwelapha ngenxa yamandla awo athile aphezulu, ukumelana nokugqwala okuphezulu kanye nokuhambisana okuhle kakhulu kwe-biocompatibility. Kodwa-ke, anqunyelwe ukusebenza kahle okuphansi, imfucuza enkulu kanye nokusebenza kabi lapho ecutshungulwa ngezindlela zendabuko zokuwenza.I-Metal injection molding (MIM)iwubuchwepheshe obusha bokubumba obuseduze nenetha, obubhekwa njengenqubo ekahle yokulungiselela i-titanium ne-titanium alloys ngoba ingakhiqiza izakhiwo eziyinkimbinkimbi, izilinganiso eziphakeme kanye nezingxenye zokunemba okuphezulu ngezindleko eziphansi. Njengamanje, inqubo evamile ye-titanium MIM eyokuqala ixube i-titanium alloy powder kanye ne-binder ukuze kutholwe ukuphakelwa okufanayo nokuzinzile, bese uthola okungenalutho okuluhlaza okuhlangabezana nezimfuneko ngokubumba umjovo. Khona-ke, ngokwezinhlelo ezihlukene zokuhlanganisa, isibopho esingenalutho esiluhlaza siyasuswa, futhi izingxenye ezidingekayo zitholakala ngokufaka i-sintering kanye nokwelashwa ngemva kokwelashwa.

Izinkinga zobuchwepheshe ze-MIM titanium alloy

Njengamanje, ucwaningo lwe-MIM titanium ne-titanium alloy selwenze inqubekelaphambili ethile, kodwa kusenezinkinga ekusetshenzisweni kwezimboni ezinkulu. Amaphuzu abalulekile ami kanje:

1. I-oxygen ephansi eyindilinga ye-titanium ne-titanium alloy powder iyabiza; Nakuba abakhiqizi basekhaya be-titanium eyindilinga ne-titanium alloy powder baye bathuthuka ngokushesha eminyakeni yamuva, lisekhona igebe elithile phakathi kwabo nobuchwepheshe obuhamba phambili emhlabeni.

2. Ukukhethwa kwe-binder kanye nenqubo yokususa amafutha; Ukukhethwa kwe-binder kunquma ubukhulu bokugcwalisa i-powder, okunomthelela oqondile ku- density, shrinkage kanye ne-surface roughness yemikhiqizo ye-sintered. Inqubo ephumelelayo yokususa amafutha isiza ukunciphisa umthelela wezinto ezingcolile, ezifana no-C no-O, futhi ithuthukise umkhiqizo.ct ukusebenza.
