Coloring Process of Colored Stainless Steel

Electrochemical coloring

1. Principle: immerse stainless steel in electrolyte, oxidize the metal surface by current to form a porous oxide film, adsorb dye, and use current density, time, electrolyte composition and other parameters to control color.
2. Advantages: The color is firmly combined with the matrix, the color is uniform and bright, high temperature resistance, and strong corrosion resistance.
3. Classic colors: blue, gold, purple, etc.

Vacuum ion plating (PVD)

1. Principle: Under vacuum environment, metal oxides are deposited on the surface of stainless steel to form a colored film through evaporation, sputtering and other technologies.
2. Advantages: Uniform and diverse colors, high hardness (HV800+), environmental protection and pollution-free.
3. Classic colors: gold, black gray, rose gold, etc.

Chemical coloring method

1. Principle: In solutions containing dichromate, sulfide, mixed sodium salt, etc., a layer of colored oxide film is formed on the surface of stainless steel through chemical reaction.
2. Features: Easy operation and low cost, but chemical solution wastewater may cause certain pollution to the environment.
3. Classic colors: bronze, blue, gold, red, green, etc.

High temperature oxidation coloring

1. Principle: Immerse in a specific molten salt, heat to 200-300℃, and form an oxide film on the surface of the stainless steel through high temperature. The thickness of the oxide film determines the color.
2. Features: Suitable for small batches of complex parts, the color changes with the thickness of the oxide film.
3. Classic colors: antique bronze, coffee and other retro effects.
