Powder metallurgy iron-based structural parts zvikamu zvezvimiro zvinogadzirwa nehupfu metallurgy tekinoroji nehupfu hwesimbi kana alloy simbi hupfu sechinhu chikuru mbimbi.Zvinodiwa zverudzi urwu rwezvikamu ndezvekuti ive yakakwana yakanaka mekiniki zvivakwa, kupfeka kuramba, kuita kwakanaka kwemachining, uye dzimwe nguva kupisa uye kuomarara kuramba.Powder metallurgy iron-based parts anoshandiswa zvakanyanya munzvimbo dzakasiyana dzehupfumi hwenyika.Kunyanya muindasitiri yemotokari, 60% kusvika 70% yepowder metallurgy iron-based parts munyika dzakabudirira anoshandiswa mumotokari, senge macamshafts, exhaust valve seats, pombi dzemvura uye magiya akasiyana.
Hunhu hwehupfu metallurgy iron-based structural parts: (1) Zvikamu zvine high dimensional kurongeka, izvo zvinogona kuva zvishoma uye pasina kucheka;(2) Porosity.Kuenzaniswa nesimbi dzakasimba, iron-based poda metallurgy zvimiro zvikamu zvakagovera zvakaenzana pores.Uniformly akagovaniswa pores anogona kubvisa mafuta ekuzora kuti avandudze anti-friction zvimiro zvechinhu, uye zvakafanana akagovaniswa spherical pores anobatsirawo kuneta kuneta kwezvikamu pasi pemamiriro ezvakawanda zvinokanganisa zvine simba diki.Nekudaro, ma pores anogona kudzikisa ma mechanic zvimiro zvezvinhu zvakaita sekusimba kwesimba, kurebesa mushure mekutyoka, uye kukanganisa kuoma, uye kukanganisa kuomarara kwechinhu, kupisa conductivity, magetsi conductivity, uye magineti permeability.Nekudaro, zvinoenderana nezvinodiwa zvekushandisa, saizi yepore uye kugovera pore kunogona kudzorwa nekugadzirisa kuumbwa kwezvinhu, saizi yechikamu uye maitiro.Nekudaro, iyo diki saizi yepore, inokwira mutengo wekugadzira.(3) Hapana kupatsanurwa kwealloying zvinhu uye yakanaka uye yakafanana crystal tsanga.Izvo zvinosanganiswa zvinhu mune iron-based structural zvinhu zvinoonekwa nekuwedzera alloying element poda nekuzvisanganisa.Pasina kunyunguduka, nhamba uye mhando dzealloying zvinhu zvakawedzerwa hazvikanganisike nekugadziriswa kwekugadziriswa uye kupatsanurwa kwe density, uye kupatsanurwa-isina alloys uye pseudo-alloys inogona kugadzirwa.Mapores anotadzisa kukura kwezviyo, saka zviyo zvesimbi-based structural materials zviri nani.
