ELECTROLESS NICKEL COATING
Electroless nickel is chemically deposited, making the coating exceptionally uniform in thickness. Electroless nickel coating provides a hard, uniform, corrosion, abrasion and wear resistant surface to protect machine components in many industrial environments. Electroless nickel is similar to stainless steel in color. It plates uniformly in recesses and cavities, and does not build up on edges.
Electroless nickel is used extensively in salvage of mis-machined parts.
The coating’s outstanding corrosion resistance leaves it virtually unaffected by petroleum products, alkalis, weak acids and many other organic liquids. Its non toxic nature has made it especially suitable for food handling equipment where both corrosion and wear resistance are required.
