Micro arc oxidation (MAO) layer (as bond coat) was successfully deposited on Mg-1%Ca alloy in KF + NaAlO2 electrolyte. In order to improve the corrosion resistance of the conventional MAO coated Mg-1%Ca alloy, air plasma sprayed (APS) nanostructure TiO2 coating (as top coat with bimodal structure) w...
