1. Mhete yeNitriding: Kuomarara kweiyo nitrided layer iri pamusoro pe950HV, iyo brittleness iri giredhi 1, ine yakanaka abrasion uye corrosion resistance, yakakwirira kuneta simba, yakakwirira corrosion resistance uye anti-seizure performance; piston mhete deformation diki.
2. Chrome-plated mhete: Iyo chrome-plated layer ine yakanaka uye yakatsetseka makristasi, kuomarara kuri pamusoro pe850HV, kusapfeka kwekudzivirira kwakanaka kwazvo, uye crisscross micro-crack network inobatsira kuchengetedza mafuta ekuzora. Zvinoenderana neruzivo rwakakodzera, "Mushure meiyo chrome plating padivi pepiston ring groove, kupfeka kwemhete groove kunogona kudzikiswa zvakanyanya. Painjini dzine tembiricha ine mwero uye mutoro, nzira dzataurwa pamusoro dzinogona kuderedza kupfekwa kwepiston ring groove ne33 kusvika 60”.
3. Mhete yePhosphating: Kuburikidza nemishonga yemakemikari, chidimbu chefirimu yephosphating inobudiswa pamusoro pemhete yepiston, iyo inogona kudzivirira chigadzirwa kubva pakuora uye kuvandudza kwekutanga kumhanya-mukati kwemhete.
4. Mhete yeoxidation: Pasi pemamiriro ekupisa kwepamusoro uye yakasimba oxidant, firimu yeoxyde inoumbwa pamusoro pezvinhu zvesimbi, iyo ine kusagadzikana kwekuora, anti-friction lubrication uye chimiro chakanaka. Kune zvakare PVD uye zvichingodaro.
