Five stainless steel surface treatment methods

Five stainless steel surface treatment methods

Although the corrosion resistance and rust resistance of stainless steel are relatively good, it is not absolute, in order to further improve the performance of stainless steel, such as hardness, the surface treatment of the material is required, and the following five surface treatment methods can be introduced to improve the performance of stainless steel.

  1. 1.ion deposition oxide or oxide method, that is, the stainless steel workpiece is placed in the vacuum coating machine for vacuum evaporation plating: for example: titanium plated watch case and watch band. It is usually golden yellow. This method is suitable for processing large quantities of products. Because of the large investment and high cost, small batch products are not cost-effective.
  2. 2.high temperature oxidation method is in a specific molten salt, immersed in the workpiece to maintain a certain process range, so that the workpiece to form a certain thickness of oxide film, and show a variety of different colors.
  3. 3.chemical method is in a specific solution, through chemical oxidation to form the color of the film, generally “because of the method” is used more, but to ensure that a batch of products are consistent in color, it must be controlled by reference telegraph.
  4. 4.electrochemical method, is in a specific solution, through electrochemical oxidation to form the color of the film, this commercial application.
  5. 5.gas phase cracking method, more complex, less used in industry.
