Top 5 Ways to Color Stainless Steel

In order to improve the wear resistance of stainless steel products, many manufacturers color stainless steel products, which mainly include: ion deposition oxides or oxides, high temperature oxidation, chemical oxidation, electrochemical oxidation, gas phase cracking and other five methods. .

First, the ion deposition oxide or oxide method is to place stainless steel workpieces in a vacuum coating machine for vacuum evaporation plating: for example: titanium-plated watch cases and watch straps. Usually golden yellow. This method is suitable for high-volume product processing. Because of the large investment and high cost, small batch products are not cost-effective.

Second, the high-temperature oxidation method is to immerse the workpiece in a specific molten salt and keep it within a certain process range, so that the workpiece forms a certain thickness of oxide film, and presents various colors.

Third, the chemical method is to form the color of the film through chemical oxidation in a specific solution. Generally, the "inco method" is used more, but if the color of a batch of products can be guaranteed to be consistent, it must be controlled by a reference telegraph.

Fourth, the electrochemical method is to form the color of the film through electrochemical oxidation in a specific solution, which is used in business.

Fifth, the gas-phase cracking method is more complicated and less used in industry.
