Abstract

Ni-Mo/Al composite coatings were obtained by electrodeposition from a Ni-Mo plating bath containing suspended Al particles. The factors including temperature, current density, and stirring rate affecting coating composition, wear, roughness and morphology have been studied. It was found that properties like as hardness, roughness, wear and the deposited Al particle content of coatings show parabolic behavior by changing each parameter. It means that there is a critical value for mentioned parameters in which properties of coatings become maximum.
