Micro arc oxidation which color is the most difficult

Red, curry color. According to query China micro-arc oxidation processing network official website public information, red, curry micro-arc oxidation processing compared to black metal color in the technical difficulty and cost is higher and more difficult. Micro-arc oxidation, also known as micro-plasma oxidation, is through the combination of electrolyte and the corresponding electrical parameters, in aluminum, magnesium, titanium and its alloy surface rely on the arc discharge generated by the transient high temperature and high pressure, the growth of a ceramic film layer based on the base metal oxide. With high material surface hardness, good wear resistance, reliable process, simple equipment, easy to operate and so on.
