I-powder metallurgy iwubuchwepheshe benqubo ekhiqiza insimbi noma isebenzisa impushana yensimbi njengezinto zokusetshenziswa, ngemva kokwakhiwa nokucwiliswa, ukukhiqiza izinto zensimbi, izinhlanganisela nezinhlobo ezihlukahlukene zemikhiqizo.

Inqubo yobuchwepheshe be-powder metallurgy
1. Ukulungiswa kwempuphu kanye nokubunjwa kokucindezela
Okuvame ukusetshenziswa pulverization mechanical, atomization, ngokomzimba namakhemikhali izindlela ukulungiselela powder.I-powder elungisiwe iyahlungwa futhi ixutshwe, izinto zokwakha zixutshwe ngokulinganayo futhi ama-plasticizers afanelekile ayengezwa, bese ecindezelwa ekubunjweni.Ama-athomu phakathi kwezinhlayiya zempushana angu-solid-phase diffusion kanye ne-mechanical occlusion, ukuze izingxenye zihlanganiswe zibe zizonke ngamandla athile..Ukucindezela okukhulu, kukhulu ukuminyana kwengxenye kanye nokwanda okuhambisanayo kwamandla.Ngezinye izikhathi ukuze kuncishiswe ingcindezi futhi kwandiswe ukuminyana kwezingxenye, indlela yokucindezela kwe-isostatic eshisayo ingasetshenziswa.

2. Ukucula
Ingxenye ecindezelweyo ifakwa esithandweni esivaliwe esinomkhathi wokunciphisa wokucwilisa, futhi izinga lokushisa le-sintering cishe liphindwe izikhathi ezingu-2/3 kuya kwezingu-3/4 endaweni yokuncibilika kwesisekelo sensimbi.Ngenxa yokusatshalaliswa kwezinhlobo ezahlukene zama-athomu ekushiseni okuphezulu, ukuncipha kwama-oxide endaweni eyimpushana kanye nokuvuselelwa kabusha kwempushana ekhubazekile, izinhlayiya zempushana ziyahlanganiswa, okuthuthukisa amandla emikhiqizo ye-powder metallurgy futhi ithole isakhiwo esifana nesama-alloys ajwayelekile.Kusenezimbotshana ezincane ezingxenyeni eziboshiwe, okuyizinto ezimboza.
Okwesithathu, emva kokucubungula
Ngaphansi kwezimo ezijwayelekile, izingxenye ze-sintered zingakwazi ukufeza ukusebenza okudingekayo futhi zingasetshenziswa ngokuqondile.Kodwa ngezinye izikhathi, okudingekayo ngemva kokucubungula kuyadingeka.Isibonelo, ukunemba kokucindezela ukwelashwa kungathuthukisa ukuminyana nokunemba kobukhulu bezingxenye;ukucima kanye nokwelashwa kokucisha indawo ezingxenyeni zensimbi ezisekelwe ku-iron kungathuthukisa izakhiwo zabo zemishini;ukucwiliswa kukawoyela noma ukucwiliswa ukuze kugcobe noma ukumelana nokugqwala.I-lubricant ewuketshezi;ukwelashwa kokungeniswa kokungena kwensimbi encibilikayo ephansi embotsheni yengxenye kungathuthukisa amandla, ubulukhuni, ipulasitiki noma ukuqina komthelela wengxenye.
Izingxenye ze-powder metallurgy zisetshenziswa kabanzi ezimbonini ezahlukahlukene: imboni yezimoto, ama-synchronizer hubs, izindandatho ze-synchronizer, ama-pulleys, ama-synchronizers;ama-bearings ahlukahlukene, amagiya e-powder metallurgy, izingxenye zesakhiwo sensimbi, njll. asetshenziswa kabanzi ekwenziweni kwemishini.
