Problems solved by technology

However, the above-mentioned magnesium alloy surface treatment technologies, such as the relatively advanced magnesium alloy plasma micro-arc oxidation technology, are still in the exploratory experiments, and the production process has high cost and low efficiency, and has not been practically applied to industrial production.
At present, most of the surface treatment of magnesium alloys in China adopts traditional anodic oxidation, chromate conversion coating, phosphate conversion coating, magnesium alloy surface electroplating and other technologies. The production process is complicated, the production cost is high, and the efficiency is low, especially the production process is serious.
