Wikipedia Overview
The chemical coloring of metals involve processes that change the color of metal surfaces with different chemical solutions. These processes can be categorized into four types:Electroplating – coating the metal surface with another metal using electrolysis.
Patination – chemically reacting the metal surface to form a colored oxide or salt.
Anodizing – electrolytic passivation process used to increase the thickness of the natural oxide layer, producing a porous surface that can accept organic or inorganic dyes easily. In the case of titanium, niobium, and stainless steel, the color formed depends on the thickness of the oxide.
Physical vapor deposition (PVD) – coating the surface with a thin film of vaporized material. This is the best method for coloring stainless steel, for the color produced is much more durable than those via other processes.
