Passivation yog siv dav hlau txheej txheej txheem los tiv thaiv corrosion. Hauv stainless hlau, cov txheej txheem passivation siv nitric acid los yog citric acid kom tshem tawm cov hlau dawb ntawm qhov chaw. Kev kho tshuaj lom neeg ua rau muaj kev tiv thaiv oxide txheej uas tsis tshua muaj kev cuam tshuam nrog huab cua thiab ua rau corrosion.
Lub hom phiaj ntawm kev ua siab ntev yog dab tsi?
