Yimuphi umehluko we-powder metallurgy kanye nenqubo yokuphonsa

Ukukhiqizwa kwe-powder metallurgyinquboiyisayensi nobuchwepheshe ecwaninga futhi ikhiqize izimpushana zensimbi ezihlukahlukene, futhi isebenziseizimpushana zensimbinjengezinto zokusetshenziswa zokukhiqiza izinto zensimbi nemikhiqizo ngokusebenzisa ukubunjwa kokucindezelwa, sintering in metallurgkanye nokucubungula okudingekayo okulandelayo.

Kuyindlela yokukhiqiza ngobuningi esebenzisa ukucutshungulwa okuncane noma okungekho nhlobo. Ingakhiqizaizingxenye zesakhiwo sensimbienobunjwa obuyinkimbinkimbi namandla aphezulu ngenani eliphansi uma kuqhathaniswa. Kuyindlela yokukhiqiza ngobuningi bokuthwala izingxenye ezizigcoba ngezindleko eziphansi.

Okuvamileizingxenye zensimbi eziyimpuphuzihlanganisa: izingxenye zezimoto, amagiya, amabhere afakwe uwoyela, izingxenye zenjini.

Ukunembaukufa kokusakazaOkwezinsimbi noma ama-alloys anamaphuzu ancibilikayo aphansi uma kuqhathaniswa, ukusakaza okunembayo nakho kungakha izingxenye ezinobumo obuyinkimbinkimbi bezinhlangothi ezintathu. Kodwa ngezinsimbi eziphikisayo nama-alloys, ama-alloys aqinile,ukubumba umjovo we-ceramic powder, njll., abakwazi ukwenza lutho, okunqunywa uhlobo lokubunjwa okunembayo. Ngaphezu kwalokho, kunzima kakhulu ukwamukela ukunemba kokusakazwa kwezingxenye zensimbi ezinosayizi omncane, udonga oluncane kanye nenani elikhulu.

Izingxenye zokusakaza ezijwayelekile: uchungechunge lwezingxenye zensimu kawoyela, uchungechunge lwezingxenye zemoto, izingxenye zezimoto ama-sreies, uchungechunge lwezingxenye zemishini.
