Effects of Electrical Parameters on Microstructure and Corrosion Resistance of Micro-arc Oxidation Coating on AZ91D Magnesium Alloys under Different Power Supply
Micro-arc oxidation (MAO) is one of the most prospective methods of surface treatment technique. The process produces thick, hard and well-adhered ceramic-like coatings to be obtained with high corrosion resistance, thermal stability and dielectric properties. Those reactions are influenced by electrolyte solution, electricity parameter processing temperature, etc, among which the electricity parameter is one of the primary factors.
Magnesium alloy micro-arc oxidation coatings are made under the differe...
