Improvement on Hardness of 6061 Al Alloy Using an Electroless Ni-P Coating
The surface morphology and hardness of electroless Ni-P alloy plating on 6061 aluminum alloys substrate in an alkaline plating bath with sodium hypophosphite as reducing agent were investigated. The effects of bath pH on the plating rate, compositions and surface morphology of theelectroless Ni-P deposits were studied. The results showed the deposition rate of the electroless Ni-P deposits increased with the rise of the bath pH, while the P content decreased. Scanning electron microcopy (SEM) of the deposits showed nodular structure for the deposits. Hardness data of the Ni-P coatings indicated that electroless Ni-P plating could obviously improve the hardness of 6061 aluminum alloy.
