According to the present invention, surface treatment can be applied to 2000 series aluminum alloys and aluminum die cast ADC12, which were conventionally considered difficult to alumite.
By forming a strong and dense composite coating on aluminum and its alloys, it can significantly improve wear resistance and corrosion resistance, and also enables machining that was previously impossible. In particular, precision finishing such as diamond grinding, flex horn, honing, and precision machining finishing is possible.
