Description

technical field [0001] The invention relates to the technical field of material surface treatment, in particular to a micro-arc oxidation treatment device and method. Background technique [0002] Micro-arc oxidation technology is a high-tech technology for in-situ growth of ceramic layers on the surface of aluminum, magnesium, titanium and other light metal alloys. By placing the metal or alloy in the electrolyte and applying an electric field to generate a large amount of discharge on the surface of the metal, a dense ceramic oxide film is formed under the joint action of thermochemistry, plasma chemistry and electrochemistry. [0003] The combination between the micro-arc oxidation film layer and the metal substrate is very firm. The structure of the micro-arc oxidation film layer is dense, and it has good hardness, wear resistance, corrosion resistance, high temperature impact resistance and electrical insulation. For mechanical equipment working in special environments...
