CADMIUM PLATING DEGRADATION WHAT IS IT?
Cadmium Plating helps protects steel materials from corrosion. Corrosion is a natural phenomenon which attacks metal by chemical or electrochemical action and converts it into a metallic compound, such as an oxide, hydroxide, or sulfate. Cadmium plating is a coating protects steel parts and provides a compatible surface when a part contacts other materials. Attack on cadmium is evidenced by a white-to-brown-to-black mottling of the surface. Cadmium degreadtion typcially found in fuel tanks.
