I-powder metallurgy inqubo yokwenza impushana yensimbi noma ukusebenzisa impushana yensimbi (noma ingxube yempushana yensimbi kanye nempushana engeyona eyensimbi) njengezinto ezingavuthiwe, ukwakhiwa nokucwiliswa, kanye nokwenza izinto zensimbi, izinto eziyinhlanganisela nezinhlobo ezahlukene zemikhiqizo.Indlela ye-powder metallurgy kanye nokukhiqizwa kwezitsha zobumba kunezindawo ezifanayo, zombili zingezobuchwepheshe be-powder sintering, ngakho-ke, uchungechunge lobuchwepheshe obusha be-powder metallurgy lungasetshenziswa futhi ekulungiseleleni izinto zobumba.Ngenxa yezinzuzo zobuchwepheshe be-powder metallurgy, isiyisihluthulelo sokuxazulula inkinga yezinto ezintsha, futhi idlala indima ebalulekile ekuthuthukisweni kwezinto ezintsha.

Ngakho-ke hlobo luni lwezinguquko olwenzekile ukusuka ku-powder metallurgy yendabuko kuya ku-powder metallurgy yesimanje?

1. Ukwehluka kwezobuchwepheshe

Ubuchwepheshe be-powder metallurgy bendabuko ikakhulukazi ngokubumba impushana kanye nokucwiliswa okujwayelekile.Ubuchwepheshe besimanje be-powder metallurgy Indlela yenqubo yokwenza nokufaka izinto zensimbi noma izingxenye zemishini ezenziwe ngempushana yensimbi, engenziwa ngokuqondile ngaphandle kokucubungula.Imikhiqizo ingalungiswa nge-laser sintering, i-microwave sintering kanye nokucindezela okushisayo kwe-isostatic kwempushana.

2. Izinto ezihlukene zokulungiselela

I-Metallurgy ye-powder yendabuko ingenza kuphela izinto ezijwayelekile ze-alloy, njengensimbi engagqwali ne-aluminium alloy, enezakhiwo eziphansi.I-powder metallurgy yesimanje ingakhiqiza izinto zokwakha ezisebenza kahle kakhulu nezinye izinto ezikhethekile.Isibonelo, ama-powder superalloy, insimbi engagqwali eyimpushana, ama-alloys esisekelo sensimbi, izinto zokushisa eziphezulu kakhulu, izinhlanganisela ze-ceramic matrix, nanomaterials, isisekelo sensimbi, i-cobalt chromium alloy materials.

3. Ubuchwepheshe bokulungiselela obusezingeni eliphezulu

Izinhlayiya zempushana ezilungiselelwe ubuchwepheshe bendabuko bokulungiselela impushana zilukhuni futhi ubukhulu bempushana abufani.Ubuchwepheshe besimanje bokulungiselela i-powder metallurgy buhlanganisa ubuchwepheshe be-jet deposition, ubuchwepheshe bokuncibilika kwe-electron beam laser, njll., kanti impushana elungisiwe incane futhi inembe kakhulu.

4. Imikhiqizo yokubumba

Ubuchwepheshe be-powder metallurgy bendabuko buphrinta imikhiqizo elukhuni ngokuqhathaniswa, nokuphrinta okuhlakaniphile kwezingxenye ezinkulu ngezinqubo ezilula.Izingxenye ezilungiselelwe ubuchwepheshe besimanje be-powder metallurgy ziyinkimbinkimbi kakhulu, hhayi nje ukuma okuguquguqukayo, kodwa futhi ubukhulu nezidingo zekhwalithi zinembile.Ububanzi bohlelo lokusebenza.
