Characterization of Ceramic Coatings on ZL114 Aluminum Alloy Prepared in Alkaline Electrolyte Adding Nano-Al₂O₃ by Micro-Arc Oxidation

Abstract:

ZL114 aluminum alloy samples were treated by micro-arc oxidation using alkaline solution added different amount of nano-Al₂O₃ to improve the surface properties. Effects of the additives were investigated by thickness, hardness, morphologies and corrosion performance. The results indicated that proper amount of nano-Al₂O₃ had certain contribution with higher corrosion performance. And adding too much nano-Al₂O₃ decreased the property of ceramic coatings.
