Conclusions 1. The microhardness of Ni−P−W coatings is 10–20% higher than that of Ni−P coatings after annealing at 400–700o for various times. The hardness is highest (HV 1120) after annealing at 400o for 1 h. 2. The Ni−P−W coatings consist of grains of the solid solution of tungsten and phosphorus in nickel and nickel phosphides. With heat treatment the grain size increases and the solid solution approaches the equilibrium condition more closely. The hardness of the coating changes correspondingly, as do the other properties.
