Chrome yakarongedzwa piston rods ingeineya yekukwana kuita mune mashandiro ezvisikwa. Iyo yetsvimbo tsvimbo inowanzo kuvezwa kubva kune yakakwirira-simba simbi kana simbi isina simba, yakasarudzwa pakuomeserwa kwayo uye kusasimba. Kumusoro kwetsvimbo kunonzwika sezviri pachena kusati kwatanga kurongedza chira mari yekuisa, ichiita kuti ive yakatsiga, yunifomu yekuvhara chromium. Uku kutarisisa hakungori shamhu yakasarudzika sechiratidzika asi inosimudzira zvakanyanya kupfeka kwayo uye kupesana kweora. Kuwedzera kwakawedzera pamusoro peiyo chrome layer inoderedza iyo yakapfeka mwero apo tsvimbo inotsvedza ichishandisa chisimbiso, ichiwedzera hupenyu hwetsvimbo uye chisimbiso. Pamusoro pezvo, iyo yakadzika-flation coefficient yeiyo chrome pamusoro inovandudza kushanda kwemuchina nekuderedza kurasikirwa kwesimba nekuda kwekukakavara. Chrome yakarongedzwa piston rods inoshandiswa mune dzakasiyana siyana dzekushandisa, kubva kumisikidzwa yemotokari kumishinari yemasipisheni, uko kuvimbika uye kuzere kweraruro.
