Surface pretreatment pamberi pesimbi passivation kurapwa

Mamiriro epamusoro uye kuchena kweiyo substrate pamberi pesimbi passivation kurapwa ichakanganisa zvakananga kunaka kweiyo passivation layer.Pamusoro peiyo substrate inowanzofukidzwa neiyo oxide layer, adsorption layer, uye inonamatira zvinosvibisa zvakaita semafuta uye ngura.Kana izvi zvisingakwanisi kubviswa zvinobudirira, zvinokanganisa zvakananga simba rekubatanidza pakati pepassivation layer uye substrate, pamwe nesaizi yekristaro, density, ruvara rwekutaridzika, uye kutsvedzereka kweiyo passivation layer.Izvi zvinogona kutungamirira kuhurema hwakadai sekuputika, kuputika, kana kuputika mumutsara wepasi, kudzivirira kuumbwa kwekatsetse uye kupenya passivation layer nekunamatira kwakanaka kune substrate.Kuwana yakachena pre-yakagadziriswa nzvimbo kuburikidza nepamusoro pekutanga kurapwa chinhu chinodiwa pakugadzira akasiyana passivation layer akasungirirwa kune substrate.
