Micro-arc oxidation (MAO) is a revolutionary method to produce hard and corrosion resistant ceramic coatings on Al, Mg, Ti and other light metals as well as their alloys. MAO method uses the effects of forming micro-arc plasma discharges on the surface of the parts treated in water electrolytic solution. Because of influences of these discharges on the parts, a multi-function protective ceramic coating forms with unique properties:
* Very high hardness
* Excellent wear resistance
* Excellent corrosion resistance
* Extremely high adhesion performance of the coating
* Dielectric property
* High thermal shock resistance
