Composite plating is a method of co-deposition of plating layer with metallic and/or non-metallic particles to improve the plating layer properties such as high corrosion resistance and photolysis of organic compounds. The properties of nickel-ceramic composite plating are significantly depend on the surface characteristics of co-deposited particles as well as the quantity in electrolyte. In this study, Ni- composite coating layer was produced by electrodeposition technique from non-aqueous eletrolyte and its surface characteristics as well as photolytic properties were investigated. The amounts of immobilized particles increased with increasing the initial particles contents in the bath. Samples electroplated with the current density of showed the significantly improved homogeneous particles distribution. The corrosion resistance of Ni- composite coating layer also improved with increaing the amounts of particles. Etched sample showed about 10% increased photolytic rate of organic matter compare to that of the non-etched.
