l MAO/EPA Technology Introduction
MAO(Micro-arc Oxidation )/EPA (Electro- Plasma Anodic Oxidation)technology is a surface treatment technology to create oxidation layer coating with ceramic structure which generated by high temperature and high pressure reaction.Test sample is immersed in oxidation bath to react with electrolyte and electricity. MAO/EPA process can apply on Al, Mg and Ti alloy.
l Process characteristics
1 Cost lower than traditional hard anodizing
2 Simple pre-treatment and good corrosion resistance
3 Green process for environment
4 Coating layer can also be control for complicated part
5 Deformation after MAO/EPA is relatively small
