Compositional optimization of chemical copper-doped nickel-phosphorus coatings

  • Published:
Inorganic Materials Aims and scope

Abstract

We have studied the physicomechanical properties (adhesion to steel, microhardness, and wear resistance) of chemical nickel-phosphorus coatings doped with a small amount (0.5–2%) of copper. The as-grown coatings have low porosity and stable composition. They are identical in mechanical properties to conventional chemical nickel-phosphorus coatings but exhibit enhanced wear resistance after heat treatment at a temperature of 600°C. Copper doping improves the corrosion resistance of the coatings in acidified chloride solutions.
