Electroless Plating

What is Electroless Plating?

Electroless plating is a chemical deposition process that deposits a metal coating—most commonly nickel-phosphorus (Ni-P) or nickel-boron (Ni-B)—onto a part’s surface without using electricity. Instead, the metal ions in the solution are reduced chemically and form a uniform coating on the substrate.

This method provides excellent uniformity, even on complex shapes, holes, and internal surfaces where traditional electroplating cannot reach evenly. Electroless plating improves wear resistance, corrosion resistance, hardness, and lubricity, making it widely used in mold components, automotive parts, electronics, aerospace, and precision machinery.
