The development of deposition of different metal processes established on electrodeposition of nickel, different alloy and composite coatings on different surfaces has attested an upsurge in interest among researchers. In latter years, these coatings have exhibited promising corrosion and wear resistance properties. Also, huge number of modern developments became most critical from macro to nano level applications. It is well known that one may shape the microstructure and the phase present in the material to recover the mechanical properties of highly pure materials, specifically metals. Co-deposition of fine particles inside a metal matrix to generate composite coatings has treated as a practical strategy to acquire enhanced mechanical properties like wear resistance, corrosion resistance and lubrication. In this work, CuO/Ni composite coatings are processed on the small cylindrical pin by electro brush plating to evaluate the wear and corrosion resistance. To examine the effects about the different parameters of processes on wear loss of CuO/Ni composite coating, L16(44) orthogonal experiment is designed and conducted with four process parameters (voltage, concentration of nanoCuO particles in g/l, temperature and thickness) which are selected as factors. Design of experiment is employed to resolve the effects of process parameters on the wear loss of composite coatings. It is concluded that concentration of CuO nanoparticle and voltage are the most significant factors for the wear loss.
