How is magnesium alloy surface treated?
For the surface of magnesium alloy material is easy to deteriorate the problem, magnesium alloy products will be finalized after the final surface treatment, at present commonly used (phosphating, passivation), spraying, vacuum transfer printing, anodic oxidation, micro-arc oxidation and other treatment methods. Magnesium alloy micro-arc oxidation treatment is currently a common surface treatment in the rail transit industry. Our company has the capacity of micro-arc oxidation treatment of ultra-long profiles (>5 meters) and acid-resistant micro-arc oxidation treatment. Widely used in military, aerospace, machinery, electronics and rail transportation and other fields.
