Ukuqina kwe-powder metallurgy sintering kuyinqubo ehlanganisa ukucwiliswa kwe-sintering kanye nokwelashwa kokushisa, okungukuthi, ngemva kokuba into ethile isinisiwe futhi ipholiswe ngokushesha, i-martensite (imvamisa engu->50%) ikhiqizwa esakhiweni se-metallographic, ukuze impahla ikhiqizwa Dlala i- indima esebenza ngempumelelo kanye nokwenza ngcono ukusebenza kahle komnotho.

Izinzuzo ze-sintering harding:

1. Inqubo yokwelapha ukushisa ingashiywa

2. Gwema ukungcola kwamafutha acishayo

3. Kulula ukuthukuthela emoyeni

4. Yehlisa ukuguquguquka komkhiqizo

5. Thuthukisa ukulawula usayizi

6. Ukwenza ngcono ukusebenza kahle kwezomnotho

7. Ukusetshenziswa kokuqina kwe-sinter

Izinto zokwakha ukuqina kwe-powder metallurgy sintered ngokuvamile zisetshenziselwa ukwakha izingxenye eziphakathi nendawo neziphezulu.Njengamanje, inqubo yokuqina kwe-sinter isetshenziswa ikakhulukazi emikhiqizweni okunzima ukuyicisha ngenxa yobukhulu nokuma.Njengezingxenye zamagiya, amahabhu okuvumelanisa, amafindo anomumo okhethekile noma anezindonga ezincane nezinye izingxenye zesakhiwo.Kafushane, ukuqina kwe-iron-based powder metallurgy sinter kungenye yezindlela eziphumelela kakhulu zokuthatha indawo yezinqubo zokwelashwa kokushisa kwe-powder metallurgy, futhi izinzuzo zako zingaphezu kokubi.Ukukhetha izinto ezifanelekile zokucwilisa kanye nokwenza lukhuni akukwazi nje ukugwema imiphumela emibi yokwelashwa kokushisa nokunciphisa izindleko, kodwa khumbula ukuthi imikhiqizo ngemva kokucwiliswa nokuqiniswa kufanele futhi ithoniswe ngesikhathi, ngokuvamile ekushiseni okupholile okungaba ngu-180 ° C.
