Significance of metal surface treatment technology

The significance of metal surface treatment technology lies in: improving product quality through surface treatment; Save precious materials and realize surface compounding of materials; Solve problems that can't be solved by a single material; Repair the overall advantages, and save energy and materials.

Metal surface treatment technology can protect and strengthen the surface of workpiece or repair waste products and processing errors without increasing or increasing excessive cost, thus improving the service life and reliability of products, improving the performance and quality of mechanical equipment and enhancing the competitiveness of products. Therefore, the metal surface treatment technology to promote high-tech development is of great significance for saving materials and energy.

Surface treatment technology mainly improves the surface properties of metal materials in two ways. One is to prepare various coatings and coatings on the surface of the substrate by surface coating technology, including electroplating, electroless plating, (electro-) chemical conversion film technology, vapor deposition technology, surfacing, thermal spraying and so on. The other is to change the structure and properties of the substrate surface through various surface modification technologies, such as surface quenching, chemical heat treatment, shot peening, high energy beam surface modification and so on.
