The electrochemical coloring method: in particular solution, formed by electrochemical oxidation of the color film.

The ion deposition of oxide coloring chemical method is: stainless steel workpieces on the vacuum coating machine for vacuum evaporation. For example: watch shell, Ti gold watch band, usually gold. This method is suitable for the processing of large quantities of products. Because the investment is big, the cost is high, the small batch product is uneconomical.

The high temperature oxidation coloring: in particular in molten salt, immersed in the workpiece is maintained in a certain process parameters, the formation of a certain thickness of oxide film, while showing a different color.

The gas phase pyrolysis: coloring method is more complex, less used in industry.
