Working conditions and oxidizing environment wear metals away. Therefore, metal surfaces are coated with a protective layer to avoid this problem.

Coating application by electrolysis method is called Galvano, and the process is called Chrome Plating if chrome is used for coating.

Industrial hard chrome plating differs from both decorative and bright chrome plating by coating thickness and its superior properties. Industrial hard chrome plating is primarily preferred on the industry because:

• It is hard; resistant to abrasion and impact.
• It is dense; durable against corrosion and chemicals.
• It has low roughness; enables high quality products that require smooth surface.
• It can be removed from surface without causing damage; can be applied repeatedly.
• It is temperature resistant; easy to maintain, does not change color and can be welded.
• Its application temperature is low; does not cause deformation like alternative surface hardening methods.
