1. Kunyudzwa
Powder metallurgy components are inherently porous.Impregnation, inozivikanwawo sekupinda, inosanganisira kuzadza pores akawanda nezvinhu zvinotevera: plastiki, resin, mhangura, mafuta, chimwe chinhu.Kuisa iyo porous chikamu pasi pekumanikidzwa kunogona kukonzera kuvuza, asi kana iwe ukanyura chikamu, chinova chisingapindire kumanikidzwa.Zvishandiso zvinoshandiswa pazvikamu zvakapinzwa zvinoenderana nezvinhu zvakaita semutengo uye mashandisiro.Semuenzaniso, mhangura inogona kuzvimba panguva yekupisa, nokudaro ichiparadza kugadzikana kwedimensional.Kunyudzwa muoiri kunogona kuzora zvikamu.Zvose zvinoenderana nezvinodiwa zvekugadzira.
2. Electroplating
Electroplating ndiyo imwe nzira kune simbi isina tsvina yeaesthetics kana inoshanda zvinodiwa - kuita kuti zvikamu zvitaridzike, kuvandudza corrosion resistance, etc. Plating inokupa unhu uhwu uku ichikubvumira "sandwich" zvinhu zvakachipa muzvikamu zvepakutanga.
3. Shot peening
Shot peening inzira yemunharaunda densification, iyo inogona kuvandudza pamusoro pezvikamu nekubvisa maburrs uye kuisa pamusoro pekumanikidza kudzvinyirira kune zvikamu.Izvi zvinogona kubatsira mune mamwe maapplication ekuneta.Kuputika kwejecha kunoburitsawo makomba madiki anoteya lubricant pamusoro pechikamu.Kuneta kutsemuka kunowanzotangwa nehurema hwepamusoro.Shot peening inogona kudzivirira kuumbwa kwekutsemuka kwepamusoro uye inogona kunonoka kuvandudzwa kwese kutsemuka.
4. Steam kurapwa
Kana yaiswa kune iron based components, steam treatment inoumba yakatetepa uye yakaoma oxide layer.Iyo oxide layer haina ngura;Chinhu chinobatirira kusimbi.Iyi layer inogona kuvandudza corrosion resistance, pressure resistance uye kuoma
