초록

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-$TiO_2$ 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 $TiO_2$ particles increased with increasing the initial $TiO_2$ particles contents in the bath. Samples electroplated with the current density of $0.5\;A/dm^2$ showed the significantly improved homogeneous $TiO_2$ particles distribution. The corrosion resistance of Ni-$TiO_2$ composite coating layer also improved with increaing the amounts of $TiO_2$ particles. Etched sample showed about 10% increased photolytic rate of organic matter compare to that of the non-etched.
