About
The product will inevitably be affected by the environment or other objects during transportation or use, resulting in partial functional failure of metal workpiece, such as oxidation, wear, corrosion, etc. The quality of the coating layer has a vital influence on the corrosion resistance，wear and abrasion resistance, degradation resistance, heat resistance, flam resistance, water resistance, electrical conductivity and even the reliability of the product. Therefore, the measurement and control of the coating is critical for control of the metal quality.
