Fabrication and Corrosion Behavior of Electroless Ni-W-P Coating on Magnesium Alloy
Ternary Ni-W-P coating was synthesized from a sulfate nickel bath. The planting rate is about 10µm/h, and the bath shows a reasonable stability. The coating shows a good adhesion to the substrate. The microhardness and corrosion resistance of the Ni–W–P deposits were found to be better when compared to plain Ni–P deposits. Also, the Ni-W-P coating with a high W content exhibits a better hardness and corrosion resistance than that with a low W content.
