This study examined the effects of alloying elements on zincate treatment and adhesion of electroless Ni-P coating onto various aluminum alloy substrate. Surface morphology of zinc deposition from the single zincate treatment and its adhesion were changed, depending on the alloying element. The zinc deposition from the double zincate treatment became thinly uniform, and the adhesion between aluminum alloy substrate and Ni-P coating was improved irrespective of the alloying element. However, the adhesion of A7075P aluminum alloy was inferior to that of other alloys.
