Powder metallurgy sintering harding ke ts'ebetso e kopanyang sintering le kalafo ea mocheso, ke hore, ka mor'a hore ntho e itseng e sirelelitsoe 'me e pholile ka potlako, martensite (hangata> 50%) e hlahisoa ka sebopeho sa metallographic, e le hore thepa e be tlhahiso ea Play a. karolo e sebetsang haholoanyane le ho ntlafatsa katleho ea moruo.

Melemo ea ho thatafatsa sintering:

1. Mokhoa oa phekolo ea mocheso o ka tlosoa

2. Qoba tšilafalo ea oli e timang

3. Ho bonolo ho halefa moeeng

4. Fokotsa deformation ea sehlahisoa

5. Ntlafatsa taolo ea boholo

6. Ntlafatsa katleho ea moruo

7. Kopo ea sinter thatafatsa

Lisebelisoa tse thatafatsang tsa phofo ea metallurgy sintered hangata li sebelisoa ho etsa likarolo tse mahareng le tse phahameng.Hona joale, mokhoa oa ho thatafatsa sinter o sebelisoa haholo-holo ho lihlahisoa tseo ho leng thata ho li tima ka lebaka la boholo le sebōpeho.Joalo ka likarolo tsa li-gear, li-synchronizer hubs, mafito a nang le sebopeho se ikhethileng kapa a masesane le likarolo tse ling tsa sebopeho.Ka kakaretso, tšepe e thehiloeng phofo metallurgy sinter harding ke e 'ngoe ea mekhoa e atlehang ka ho fetisisa ea ho nka sebaka sa mekhoa ea phekolo ea mocheso oa phofo ea metallurgy,' me melemo ea eona e feta mefokolo ea eona.Ho khetha lisebelisoa tse loketseng bakeng sa sintering le ho thatafatsa ho ke ke ha qoba feela liphello tse mpe tsa phekolo ea mocheso le ho fokotsa litšenyehelo, empa hopola hore lihlahisoa ka mor'a ho sintering le ho thatafala le tsona li tlameha ho halefa ka nako, hangata ka mocheso oa mocheso o ka bang 180 ° C.
