Chrome yakapfekwa piston tsvimbo inogadzirwa kuti iite zvakakwana mumashandisirwo ane simba.Nheyo yetsvimbo inowanzogadzirwa kubva kune yakakwirira-yakasimba simbi kana simbi isina tsvina, inosarudzwa nokuda kwekuoma kwayo kwekuzvarwa uye kusimba.Iyo pamusoro petsvimbo inokwenenzverwa zvine hungwaru isati yaitwa chrome plating process, kuve nechokwadi chekutsvedzerera, yunifomu yakapetwa yechromium.Iyi plating haingopi tsvimbo kutaridzika kwayo inopenya asi zvakare inosimudzira kupfeka kwayo uye kusaita ngura.Kuwedzera kuoma kwepamusoro kunopihwa ne chrome layer kunoderedza chiyero chekupfeka kana tsvimbo inotsvedza nepakati pechisimbiso chayo, ichiwedzera hupenyu hwese tsvimbo nechisimbiso.Pamusoro pezvo, iyo yakaderera friction coefficient ye chrome pamusoro inovandudza kushanda kwemuchina nekudzikisira kurasikirwa kwesimba nekuda kwekupokana.Chrome yakaputirwa piston tsvimbo dzinoshandiswa mumhando dzakasiyana siyana dzekushandisa, kubva pakumiswa kwemotokari kuenda kumakina emaindasitiri, uko kuvimbika uye hupenyu hurefu hwakakosha.
