Muupfu metallurgy,poda metallurgy kugadzira maitirokana kushandiswa seyakagadzirwa kugadzira simbi zvinhu, zvinoumbwa zvinhu, uye zvakasiyana zvigadzirwa mushure mekugadzirwa uye sinterized. Powder metallurgy, inova chikamu cheupfu simbi sintering, inobatana nekugadzirwa kweceramics. Nekuda kweizvozvo, akati wandei ekugadzira sintering simbi yeupfu inogona kushandiswa kugadzira zvinhu zveceramic.
1. Kugadzirira kwehupfu hwehupfu. Nzira dziripo dzekugaya dzinogona kukamurwa kuita zvikamu zviviri: nzira dzemuchina uye physicochemical nzira. Mechanical nzira dzinogona kukamurwa kuva: mechanical kupwanya uye atomization; Nzira dzemuviri uye dzemakemikari dzakakamurwa kuita electrochemical corrosion nzira, nzira yekudzikisa, kemikari nzira, yekudzikisa-kemikari nzira, vapor deposition nzira, liquid deposition nzira uye electrolysis nzira. Pakati pavo, nzira yekudzikisa, nzira yeatomization uye electrolysis nzira inoshandiswa zvakanyanya.
2. Hupfu hunoumbwa husina chinhu nechimiro chaunoda. Chinangwa chekuumba ndechekupa iyo isina chinhu chimwe chimiro uye saizi, uye kupa iyo imwe density uye simba. Nzira dzekugadzira dzakapatsanurwa kuita dzvinyiriro yekuumba uye isiri-kumanikidza kuumba. Pressure molding inoshandiswa zvakanyanya mukumanikidza kuumba.
3. billet sintering. Danho rakakosha kupindaupfu metallurgy sinteringtekinoroji yevira iri kupisa. Iyo billet yakasvibirira inogona kucheneswa mushure mekunge yaumbwa kuti ipe iyo inodiwa michina uye yemuviri maitiro. Unit sintering uye multi-system sintering mapoka maviri ekuridza. Iyo tembiricha yekupisa yakadzikira pane inonyungudika yesimbi uye alloy inoshandiswa kune yakasimba state sintering yeunit system uye akawanda-element system. Tembiricha yekunyunguduka yechikamu chemvura sintering ye-multi-component masisitimu inowanzokwira kupfuura nzvimbo yekunyungudika ye fusible component asi yakaderera pane inonyungudika yerefractory component. Kune akasarudzika sintering matekiniki akadai akasununguka kupfura, kunyunguduka kunyunguduka, uye kupisa kudzvanya kuwedzera kune yakajairwa sintering.
4. kutevera kurapwa kwechigadzirwa. Kutevera sintering, nzira dzakasiyana dzekugadzirisa dzinogona kushandiswa zvichienderana nezvinodiwa zvechigadzirwa chekupedzisira. zvakadai sekugadzira, kupisa kupisa, electroplating, kupedza, nezvimwe zvakadaro. Pamusoro pezvo, mumakore achangopfuura, poda metallurgy sintering muchoto zvinhu zvakagadziridzwa zvichishandiswa kukungurutsa, forging, uye dzimwe nzira nyowani, uye mibairo yakanaka yakawanikwa.
