Colored stainless steel coils
have become increasingly popular in modern architecture, interior design, and industrial applications.
W
hat exactly goes into creating these eye-catching finishes? This article delves into the detailed manufacturing process of colored stainless steel coils, from coating techniques to finishing options.
Physical Vapor Deposition
Sputtering Coating
The process of bombarding a metal or non-metal Target with ions to "sputter" atoms or molecules on the surface of the target from the material and deposit them onto the surface of the substrate to form a film.
Ion Implantation
Based on ion implantation, the interface between the film and the substrate is weakened, the adhesion is strong, the coating is strong, the coating is not easy to fall off, and the coating is uniform and dense. Ion implantation has good diffraction, can form a thin film on the material, plated various hard films, and has a strong anti-wear performance.
Chemical Coloring
Through the oxidation of an oxidizing agent such as dichromate acid solution, an oxide film is formed on the surface of stainless steel. This transparent film produces different colors due to the interference of light.
Electrochemical Coloring
The metal is immersed in a specific electrolyte and, by applying an electric current, oxidation or electrochemical deposition occurs on the metal surface. Materials such as stainless steel will generate a uniform oxide film on the surface during the electrolysis process. This film shows different colors through the interference effect of light.
Spray Coating
The coating is sprayed evenly onto the surface of the material by a specialized device, such as a spray gun, to form a decorative or protective coating.
