Abstract
Ni-W/ZrO2 nanocomposite coatings were prepared by electrodeposition in Ni-W plating bath containing ZrO2 nanoparticles. The influences of preparation parameter, such as ZrO2 nanoparticles concentration, current density and stirring rate, on weight percentage of codeposited ZrO2 nanoparticles in the nanocomposite coatings were investigated. The surface morphology of Ni-W/ZrO2 nanocomposite coating was characterized by scanning electron microscopy (SEM). The microhardness, wear resistance and corrosion resistance properties of Ni-W/ZrO2 nanocomposite coatings were studied. The results indicated that the addition of ZrO2 nanoparticles leads to an increase in microhardness and wear resistance of the nanocomposite coatings and a reduction in the wear weight loss. The corrosion behaviour of Ni-W/ZrO2 nanocomposite coatings was evaluated by the anodic polarization curves and weight loss measurements. The results revealed that Ni-W/ZrO2 nanocomposite coating has better corrosion resistance than the Ni-W alloy coating.
