In the paper, Ni-Al2O3 coatings were prepared by HVO/AF . The microstructure and composition of the Ni-Al2O3 coatings were investigated by metallographic microscope, scanning electron microscope and X-rayed diffraction, Bonding strength and hardness and mechanics properties were tested. The experimental results show the Ni- Al2O3 coatings possessed high microhardness and higher bonding strength with substrate and excellent comprehensive mechanical properties.
