Buyini ubuchwepheshe be-powder metallurgy?

Ubuchwepheshe be-powder metallurgy baqala ukusetshenziswa e-United States ngo-1870. Yasebenzisa impushana yensimbi njengento eluhlaza, yabe isicindezela ama-alloy bearings e-copper-lead ukuze ibone ubuchwepheshe bokuzithambisa be-bearing, futhi yakhiqiza izingxenye nezingxenye ezihlukahlukene ngokucindezela. futhi sintering.Inqubo yobuchwepheshe be-powder metallurgy izwakala ingajwayelekile kuwo wonke umuntu, kodwa uma ngemva kwencazelo yami, kuyoba lula kuwe ukuyiqonda.

Inqubo eyisisekelo yobuchwepheshe be-powder metallurgy
Izinto eziyinhloko ziyi-powder yensimbi enhle, khona-ke i-powder yengezwa ekubunjweni okudingekayo, bese imodeli yakhiwe (umjovo) noma ingcindezi, futhi ekugcineni ingxenye oyifunayo kanye nomphumela ingatholakala ngokufaka i-sintering.Ezinye izingxenye zidinga ukucutshungulwa kwangemuva.

Uyini umehluko wezingxenye ze-MIM ne-PM powder metallurgy?
1: Ukubumba umjovo we-powder metallurgy
Ukubumba komjovo we-powder metallurgy kwazalelwa eCalifornia ngo-1973, okubizwa ngokuthi i-MIM.Kuwuhlobo olusha lobuchwepheshe bokubumba i-powder metallurgy olusungulwe ngokuhlanganisa ubuchwepheshe bokubumba umjovo wepulasitiki nomkhakha we-powder metallurgy.Inqubo yokubumba umjovo we-powder metallurgy iseduze kakhulu nobuchwepheshe be-powder metallurgy.Okokuqala, i-powder eqinile kanye ne-organic binder ixutshwe ngokulinganayo, bese ifudumala futhi ifakwe epulasitiki ekushiseni okuphezulu kwama-degree angu-150.Imishini yokubumba umjovo isetshenziselwa ukujova isikhunta emgodini, bese iqinisa futhi imise.Indlela yokubola isusa isibophezelo endaweni engenalutho, futhi ekugcineni, njenge-powder metallurgy, izingxenye ezinembayo zikhiqizwa ngokucwiliswa.

2: Ukucindezela i-powder metallurgy
Ukubumba kokucindezelwa kwe-powder metallurgy ukugcwalisa isikhunta ngempushana ngamandla adonsela phansi, bese usikhipha ngomfutho womshini.Ingenye esetshenziswa kabanzi ezinhlelweni ezisebenzayo zezimboni.Ukucindezela isikhunta sensimbi esivalwe ngokubandayo, ukucindezela okubandayo kwe-isostatic, ukucindezela okushisayo kwe-isostatic, nokucindezela okufudumele konke kuyisici sokucindezela.Nokho, ngenxa yokuthi ingacindezelwa kuphela phezulu naphansi kuzo zombili izinhlangothi, ezinye izingxenye zesakhiwo eziyinkimbinkimbi azikwazi ukukhiqizwa noma zingenziwa kuphela izikhala.

Izingxenye eziningi zisebenzisa umjovo wokubumba noma ukucindezela ukubumba, futhi ukusebenza kwengxenye yokugcina kuzohluka.Uma ungakakwazi ukuhlukanisa kahle, ungangabazi ukusithinta i-Jingshi New Materials ukuze ubonisane.
