Isinyithi se-nickel sinozinzo oluphezulu emoyeni, isakhono esinamandla sokwenza i-passivation, sinokwenza ifilimu encinci ye-passivation emoyeni, inokumelana nokubola kwe-alkali kunye ne-acids, ukwenzela ukuba imveliso ibe nekhemikhali ezinzileyo emsebenzini kunye nokusingqongileyo kwe-alkali, akukho lula ukuyikhupha, ingaba kuphela i-oxidized ngaphezu kwama-600℃; umaleko we-nickel plating unonamathela olomeleleyo, akukho lula ukuwa; Umaleko we-nickel plating unokwenza umphezulu wezinto ube nzima, unokuphucula ukuxhathisa imveliso kunye ne-asidi kunye ne-alkali yokumelana nomhlwa, ukuxhathisa imveliso yokunxiba, ukubola, ukusebenza kokuthintela umhlwa kuhle kakhulu.
