Izingxenye zesakhiwo ezisekelwe ku-iron powder ziyizingxenye zesakhiwo ezikhiqizwa ubuchwepheshe be-powder metallurgy nge-iron powder noma i-alloy steel powder njengento eluhlaza.Izidingo zalolu hlobo lwezingxenye ziwukuba nemishini emihle ngokwanele, ukumelana nokugqokwa, ukusebenza kahle kwemishini, futhi kwesinye isikhathi ukumelana nokushisa nokugqwala.Izingxenye zensimbi ezenziwe nge-powder metallurgy zisetshenziswa kakhulu emikhakheni eyahlukene yomnotho wezwe.Ikakhulukazi embonini yezimoto, u-60% kuya ku-70% wezingxenye ezisekelwe ku-iron powder emazweni athuthukile zisetshenziswa ezimotweni, njengama-camshaft, izihlalo zamavalvu e-exhaust valve, izimpompi zamanzi namagiya ahlukahlukene.

Izici ze-powder metallurgy iron-based structural izingxenye: (1) Izingxenye zinokunemba okuphezulu kwe-dimensional, okungaba kuncane futhi ngaphandle kokusikwa;(2) I-Porosity.Uma kuqhathaniswa nezinsimbi eziminyene, izingxenye zesakhiwo se-iron-based metallurgy metallurgy zihlukanise izimbotshana ngokulinganayo.Izimbotshana ezisatshalaliswe ngendlela efanayo zingaqeda uwoyela wokugcoba ukuze kuthuthukiswe izakhiwo zokulwa nokungqubuzana kwempahla, futhi izimbotshana eziyindilinga ezisatshalaliswe ngokulinganayo nazo zisiza ukumelana nokukhathala kwezingxenye ngaphansi kwesimo semithelela eminingi enamandla amancane.Kodwa-ke, izimbotshana zinganciphisa izici zokulungisa zezinto ezinjengamandla aqinile, ubude ngemva kokuphuka, nokuqina komthelela, futhi kuthinte ukumelana nokugqwala kwempahla, ukuqhutshwa kwe-thermal, ukuqhutshwa kukagesi, nokungena kazibuthe.Kodwa-ke, ngokwezidingo zohlelo lokusebenza, usayizi we-pore kanye nokusabalalisa kwe-pore kungalawulwa ngokulungisa ukwakheka kwezinto ezibonakalayo, usayizi wezinhlayiyana kanye nenqubo.Kodwa-ke, usayizi wembotshana omncane, izindleko zokukhiqiza ziphezulu.(3) Akukho ukuhlukaniswa kwezakhi ze-alloying kanye nezinhlamvu zekristalu ezinhle nezifanayo.Izakhi ze-alloying ezintweni zesakhiwo esekwe ku-iron zibonakala ngokungeza izimpushana ze-alloying element futhi zixutshwe.Ngaphandle kokuncibilika, inombolo nezinhlobo zezakhi ze-alloying ezingeziwe azithintwa imikhawulo ye-solubility kanye nokuhlukaniswa kwabantu, futhi ama-alloys angahlukaniswanga kanye nama-pseudo-alloys angalungiswa.Ama-pores avimbela ukukhula kwezinhlamvu, ngakho-ke izinhlamvu zezinto zokwakha ezisekelwe ku-iron ziba ngcono.
