Kureurura kwekunyepedzera kusati kwatanga simbi kupatsanurwa kurapwa

Mamiriro ekunze uye kuchena kweiyo substrate kusati kwatanga kurapwa kwesimbi kwekurapa kunokanganisa zvakananga kunaka kweshoko rePassivation. Kumusoro kweiyo substrate kunowanzoiswa pamwe nehodhi yehusiku, adsorption layer, uye kuomerera polutants yakadai semafuta uye ngura. Kana izvi zvisingakwanise kubviswa zvinobudirira, iko kushamwaridzana simba pakati peiyo fesivation layer uye substrate, pamwe neiyo crystalline saizi, density, kutaridzika kwemavara, uye kutapira kweshoko rePassivation. Izvi zvinogona kutungamira kuremara senge bubbling, kubhururuka, kana kukanda mapfumo pasi, kudzivirira kuumbwa kwenzvimbo yakatsiga uye yakajeka yekushambidzika kune iyo substrate. Kuwana yakachena pre-yakagadziriswa pamusoro penzvimbo pre-kurapa ndiyo prequisite yekuumba akasiyana-siyana ekusangana zviyero zvakasungwa zvakasungwa kune substrate.
