Research on functional ceramic coatings prepared by micro-are oxidation

Micro-arc oxidation,also called anodic oxidation technology or plasma-enhanced electrochemical ceramic coating technology,which is a new and efficient surface treatment technology.Plenty of researches have been done on micro-arc oxidation in recent years,however,most of them are focused on the performance evaluation,characterization and testing of ceramic layers.Time-varying changes on factors,such as electric parameter,coating thickness,surface roughness,coating composition and microstructure during micro-arc oxidation process are systematically introduced in the research of growth characteristics.
