Powder metallurgy sintering lukhuni yinkqubo edibanisa sintering kunye nobushushu unyango, oko kukuthi, emva kokuba izinto ezithile sintered kwaye ngokukhawuleza lupholile, martensite (ngokuqhelekileyo> 50%) iveliswa kwisakhiwo metallographic, ukuze izinto kwimveliso Dlala a indima esebenzayo ngakumbi kunye nokuphucula ukusebenza kakuhle kwezoqoqosho.

Iingenelo zokuqiniswa kwe-sintering:

1. Inkqubo yokunyanga ukushisa inokushiywa

2. Kulumkele ukungcoliseka kweoli yokucima

3. Kulula ukucaphuka emoyeni

4. Ukunciphisa ukuguqulwa kwemveliso

5. Phucula ulawulo lobungakanani

6. Ukuphucula ukusebenza kakuhle kwezoqoqosho

7. Ukusetyenziswa kokuqina kwe-sinter

Izinto zokuqiniswa kwepowder sintered zisetyenziswa ukwenza iindawo ezinoxinano oluphakathi noluphezulu.Okwangoku, inkqubo yokuqina kwe-sinter isetyenziswa ikakhulu kwiimveliso ekunzima ukuzicima ngenxa yobukhulu kunye nokumila.Njengeenxalenye zegiya, iihabhu ze-synchronizer, amaqhina anokwakheka okukhethekileyo okanye abhityileyo kunye namanye amalungu olwakhiwo.Isishwankathelo, i-iron-based powder metallurgy sinter ukuqina yenye yezona ndlela zisebenzayo zokubuyisela inkqubo ye-powder metallurgy yokushisa ubushushu, kwaye iingenelo zayo zigqwesa iintsilelo zayo.Ukukhetha izinto ezifanelekileyo zokucoca kunye nokuqina akunakuphepheka kuphela imiphumo emibi yonyango lokushisa kunye nokunciphisa iindleko, kodwa khumbula ukuba iimveliso emva kokucoca kunye nokuqina kufuneka zihlanjululwe ngexesha, ngokuqhelekileyo kwiqondo lokushisa elimalunga ne-180 ° C.
