Micro-arc oxidized surface treatment is as follows:
1, the process is simple, covers an area of small, strong processing capacity, high production efficiency.
2, non-toxic and environmentally friendly, the liquid does not contain toxic substances and heavy metals. High recycling efficiency.
3, improve the surface hardness of the workpiece, improve wear resistance.
4, excellent corrosion resistance and insulation.
5, different characteristics of the oxide film layer can be obtained by changing the process parameters. Such as densification, film thickness, corrosion resistance and insulation.
6, by changing the liquid composition, the film layer can have special properties or obtain different colors.
Characteristics of micro-arc oxidation
1, substantially improve the surface hardness of the material, micro-hardness of 1000 to 2000HV, up to 3000HV, comparable to carbide, greatly exceeding the hardness of heat-treated high-carbon steel, high-alloy steel and high-speed tool steel.
2, good wear resistance.
3, good heat resistance and corrosion resistance. This fundamentally overcomes the shortcomings of aluminum, magnesium, titanium alloy materials in the application, so the technology has a broad application prospects.
4, has good insulation properties, insulation resistance up to 100MΩ.
5, the solution is environmentally friendly, in line with environmental emission requirements.
6, stable and reliable process, simple equipment.
7, the reaction is carried out at room temperature, convenient operation, easy to master.
8, the substrate in situ growth of ceramic membrane, combined with strong, dense and uniform ceramic membrane.
