Abstract

In this study, the use of nickel fluoride tetrahydrate (NiF ₂ ·4H ₂ O) as a surface activator and sealant at the same time for the coating of electroless nickel-phosphorus (Ni-P) on anodized aluminum alloy AA1050 is proposed. The usage of the activator resulted in more efficient deposition of Ni-P, improved adhesion properties, and increased wear and friction behavior as opposed to non-activated conditions. Scanning electron microscopy (SEM) and confocal laser microscopy (CLM) analyses of ultramicrotome-cut cross sections of Ni-P coated specimens, surface-activated by NiF ₂ ·4H ₂ O, revealed a more well-structured metal-coating interface as opposed to non-activated conditions.
