| Abstract: | Anodized AZ31 magnesium alloy substrates were coated with polyurethane via electrophoresis.Resultant polyurethane coatings were then incorporated with powders of alumina,aluminum and zinc respectively under compression to generate composite coatings containing high solid contents.The microstructure and corrosion resistance of the composite coatings were analyzed using a scanning electron microscope,an electrochemical test rig and a salt-spray chamber.Results show that the solid particles are tightly embedde... |
