Cov txheej txheem saum npoo thiab kev huv ntawm lub substrate ua ntej kev kho cov hlau passivation yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov txheej txheem passivation.Qhov saum npoo ntawm lub substrate feem ntau yog them nrog oxide txheej, txheej adsorption, thiab adhering pollutants xws li roj thiab xeb.Yog tias cov no tsis tuaj yeem raug tshem tawm tau zoo, nws yuav cuam tshuam ncaj qha rau kev sib koom ua ke ntawm cov txheej txheem passivation thiab cov substrate, nrog rau cov crystalline loj, ntom, xim xim, thiab smoothness ntawm passivation txheej.Qhov no yuav ua rau muaj qhov tsis xws luag xws li bubbling, tev, lossis flaking hauv cov txheej txheem passivation, tiv thaiv kev tsim cov txheej txheem du thiab ci ci nrog adhesion zoo rau lub substrate.Tau txais cov txheej txheem ua ntej kom huv si los ntawm kev kho qhov chaw ua ntej yog qhov yuav tsum tau ua ua ntej rau kev tsim ntau yam txheej txheej passivation ruaj khov rau cov substrate.
