1. Kuiswa pamuviri

Powder metallurgy components are inherently porous.Impregnation, iyo inonziwo kupinza, inosanganisira kuzadza akawanda epores ne: plastiki, resin, mhangura, mafuta, chimwe chinhu.Kuisa porous chikamu pasi pekumanikidzwa kunogona kukonzera kudonha, asi kana iwe ukarovedzera chikamu, chinova chinomanikidza-chakasimba.Izvo zvinoshandiswa kuisa pamuviri chikamu zvinoenderana nezvinhu zvakaita semutengo uye kushandiswa.Kunyudzwa kweoiri kunobvumira zvikamu kuti zvingozvizora.Zvose zvinoenderana nezvinodiwa zvekugadzira.

2. Electroplating

Plating ndiyo imwe nzira kune Stainless simbi nokuda aesthetic kana kushanda zvinodiwa - kuita chikamu zvikuru nemaziso uye kunatsiridza ngura kuramba etc. Plating anokupa unhu uhwu uku achikubvumira kuti "sandwich" zvakachipa zvinhu kupinda chepakutanga chikamu.

3. Shot peening

Shot peening inzvimbo yakasarudzika densification process inovandudza pamusoro pechikamu nekubvisa maburrs uye nekuisa pamusoro compressive stress kune chikamu.Izvi zvinogona kubatsira mune mamwe maapplication ekuneta.Sandblasting yakagadzirawo mahomwe madiki anoteya lubricant pamusoro pechikamu.Kuneta kutsemuka kunowanzotanga nekuda kwekuremara kwepamusoro.Shot peening inogona kudzivirira kuumbwa kwekutsemuka kwepamusoro uye kunogona kunonoka kuvandudzwa kwekutsemuka kwakawanda.

4. Steam kurapwa

Kana yaiswa kune iron-based components, steam treatment inogadzira yakatetepa, yakaoma oxide layer.Iyo oxide layer haina ngura;chinhu chinonamira nesimbi.Iyi layer inogona kuvandudza: corrosion resistance, pressure resistance, kuoma
