Sinsimbi engagqwali izingxenye ze-sintered iyinsimbi engagqwali ekhiqizwa i-powder metallurgy.Kuyi-powder metallurgy material engenziwa insimbi noma izingxenye.Izinzuzo zayo ukunciphisa ukuhlukaniswa kwezakhi ze-alloying, ukulungisa i-microstructure, ukuthuthukisa ukusebenza, ukonga izinto zokusetshenziswa, ukonga amandla nokunciphisa izindleko.

Inqubo yokukhiqiza ye-powder metallurgy steel stainless steelizingxenye.

Isinyathelo sokuqala ukunquma inqubo yokukhiqiza ye-powder yokuncibilikisa izigxivizo zensimbi engagqwali: ukwakheka kwesikhunta kanye nokuzimisela kwempahla eluhlaza-ukukhiqiza-isikhunta-ukufakwa kwempahla eluhlaza ukuxuba-isikhunta ukufakwa nokulungisa umshini ukukhiqiza-izinto zensimbi engagqwali kufanele zifakwe esithandweni somlilo we-vacuum-machining- deburring-prevention I-rust-impregnated oil-spection amaphakheji afanelekayo.

I-powder metallurgy stainless steel seals ngokuvamile yenziwa ngensimbi engagqwali i-SS316L noma i-SS304L.Ngesikhathi esifanayo, ukuze kuncishiswe i-porosity, i-2% kuya ku-8% i-alloy-based alloy yengezwe ku-304 noma i-316 yensimbi engagqwali powder.Ngenxa yezinga eliphansi lokuncibilika kwethusi, izosetshenziswa ku-960℃.Isigaba se-liquid siqala ukwakheka, futhi zonke zakha isigaba samanzi lapho izinga lokushisa lifinyelela ku-1000℃.Lapho izinga lokushisa liphakeme kunendawo yokuncibilika yethusi, ukugeleza kwesigaba soketshezi kwenza izimbotshana ezingaphezulu ziqhubeke zi-spheroidize futhi zishwabane;ngenxa yokuthi ithusi linokumanzisa okungcono ku-matrix yensimbi engagqwali, ingasatshalaliswa Ngokulinganayo ku-substrate yensimbi engagqwali, ama-pores omzimba we-sintered ancishiswa kakhulu, futhi ukusebenza kokuvala kuthuthukiswa kakhulu.

Izindawo zokusebenzisa izingxenye zensimbi engagqwali ye-powder metallurgy: izimoto: izingxenye zamabhuleki, ukukhiya ibhande lesihlalo;izinto zasendlini: imishini yokuwasha izitsha ezizenzakalelayo, imishini yokuwasha, imishini yokulahla udoti, amajusi nezinye izingxenye zemishini yasendlini;izingxenye zezinsimbi zezimboni, izingxenye ezincane ezihlukahlukene zemishini.
