Ubume bomphezulu kunye nokucoceka kwe-substrate phambi kokuba unyango lwe-metal passivation luya kuchaphazela ngokuthe ngqo umgangatho we-passivation layer.Umphezulu we-substrate ngokubanzi ugqunywe ngumaleko we-oxide, umaleko we-adsorption, kunye nokubambelela kungcoliseko olunje nge-oyile kunye nomhlwa.Ukuba ezi zinto azikwazi ukususwa ngokufanelekileyo, ziya kuchaphazela ngokuthe ngqo amandla okudibanisa phakathi kwe-passivation layer kunye ne-substrate, kunye nobukhulu be-crystalline, ubuninzi, umbala wokubonakala, kunye nokugudiswa komgca we-passivation.Oku kunokukhokelela kwiziphene ezifana nokubhubhuza, ukuxobuka, okanye ukugqabhuka kuluhlu lwe-passivation, ukuthintela ukubunjwa komgangatho ogudileyo kunye oqaqambileyo wokugqitha kunye nokubambelela kakuhle kwi-substrate.Ukufumana umphezulu ococekileyo owenziwe kwangaphambili ngonyango lwangaphambili yimfuneko yokwenza iileya ezahlukeneyo zokudlula ezidityaniswe ngokuqinileyo kwi-substrate.
