Modification of physical and mechanical properties of Zn-Ni coatings by x-ray radiation

This paper presents the results of the study of physical and mechanical properties of the Zn-Ni alloy coatings modified by X-ray radiation. Non-monotonic dependence of the mechanical characteristics of coatings on the acidity of electrolyte used for deposition of Zn-Ni alloys was found. It was established that the effect of X-rays leads to the increase of microhardness and to the decrease of the coefficient of friction of the coatings deposited from neutral and weakly acidic electrolytes. The inverse relationship for the coatings deposited from acidic electrolyte was observed.
