Abstract

THE TUNGSTEN content and current efficiency of Ni-W alloy deposits from pulse plating I were lower than those from direct-current (dc) plating at an average current density of 10A/dm². Deposits with a higher tungsten content have an amorphous structure. It is shown that pulse plating can improve surface roughness. Furthermore, the hardness and corrosion resistance of deposits in 3% NaCl solution with pH6.8 increased with tungsten content. Also, the weight-loss data from the dry wear show a good reciprocal correlation with hardness.
