I-Powder Metallurgy Umkhiqizi Wensimbi Engagqwali Wesithombe Esifakiwe Esingokwezifiso

Powder Metallurgy Stainless Steel Umkhiqizi ngokwezifiso

Incazelo emfushane:

I-powder metallurgy insimbi engagqwali ingenziwa izingxenye. Amanzi ensimbi engagqwali ancibilikiswa esithandweni sokungenisa ageleza aphume embobeni evuzayo yomlomo womlomo, ahlambuluke ngamanzi anomfutho ophezulu, futhi ajiye ukuze athole impushana yensimbi engagqwali. Impushana yayiphelelwe amanzi, omisiwe, alinganisiwe futhi ashunquliwe, futhi ukuminyana kwenqwaba yamanzi empushana yensimbi engenasici kwakungu-2.5 ~ 3.2g/cm. Yakhiwa ngaphansi kwengcindezi engu-550 ~ 830MPa. Ukuhlanganisa kufakwa i-hydrogen noma emkhathini we-ammonia obolile ngephuzu lamazolo. -45~-50℃.I-vacuum sintering nayo ingasetshenziswa, izinga lokushisa le-sintering lika-1120 ~ 1150℃.Uma izakhiwo ezinhle zemishini kanye nokumelana nokugqwala kuyadingeka, ukushisa kwe-sintering kufika ku-1315C kuyasetshenziswa.

Insimbi engagqwali ye-Powder Metallurgy

I-Powder metallurgical stainless steel ingenziwa ibe yi-steel.Amanzi ensimbi engagqwali ayenziwe athomu abe yimpushana enomfutho we-nitrogen ophezulu.Izinhlayiya zempuphu zaziyindilinga, ukuminyana kokupakishwa okuxekethile kwakungaba ngu-4.8g/cm, kanti okuqukethwe komoya-mpilo wempushana kwakungaphansi kuka-100 × 10. Impushana yensimbi engenasici nayo ingakhiqizwa ngokujikeleza kwe-electrode pulverization ene-oxygen content (40 ~ 70)×10.Lezi zimpushana zensimbi engagqwali zifakwa ku-casing, vacuum zivaliwe, ukucindezela okubandayo kwe-isostatic ku-5kPa pressure, bese kuba ukushisa okushisayo kwe-isostatic ku-1050℃ kanye nokucindezela okungu-2kPa ukuze kugxiliswe impahla.Ukuhlanganiswa okubandayo kwe-isostatic nakho kungashiswa zibe izinti ezihlangene namapayipi ku-1200 ℃. Uma kuqhathaniswa nensimbi evamile nensimbi engagqwali ekhandiwe, ukuhlukaniswa kwezakhi ze-nickel, i-chromium kanye ne-molybdenum ensimbi engagqwali ephathwa ngempushana kuncane, usayizi wokusanhlamvu mncane kakhulu, futhi ukufakwa kwe-sulfide kuhle futhi ngokulinganayo. distributed.Ngakho-ke iyathuthukiswa:

1. Izingxenye zensimbi engagqwali eziyimpushana

2. Insimbi engagqwali powder metallurgy izingxenye

3. Izakhiwo zemishini nokumelana nokugqwala.

Izinsimbi ezikhethekile ezingagqwali ezine-molybdenum ephezulu, i-nickel, i-nitrogen ne-manganese zisetshenziselwa ukuthuthukisa ukumelana nokugqwala kanye namandla ezindaweni ezinzima zasogwini.
