摘要：Ni-ZrO2 nanocomposite coatings were obtained by electroplating using Watts nickel baths with different concentrations of ZrO2 particles in suspension. The substrate was horizontally immersed in the bath to enhance the ZrO2 content in the Ni matrix. X-ray diffraction analysis showed that the presence of ZrO2 leaded to the intensity of crystal face (311) sharply increasing, and, simultaneously, the crystal orientation of (220) was greatly decreased. Observation using scanning electron microscopy indicated that the incorporation of ZrO2 nanoparticles also caused changes in the morphology and size of Ni grains. Although agglomeration of ZrO2 nanoparticles occurs in the deposits, the nanocomposites exhibited a great improvement in wear resistance compared to those of unreinforced Ni coating.
