Abstract
n-ZrO2/Ni composite coatings were prepared by electrodeposition on AZ91D magnesium alloy surfaces which was plated by Ni-P.The surface morphology,section morphology and corrosion resistance of the composite coatings were compared and analyzed.The results showed that the n-ZrO2/Ni composite coatings were more compact and smooth and its grains were smaller than pure Ni coatings.The n-ZrO2/Ni composite coatings had an evident passivation region and showed excellent corrosion resistance
