Electroless nickel plating
Electroless nickel plating is a technique used to deposit a nickel layer on metal surfaces. This method is based on a chemical reduction reaction, where a nickel-containing chemical solution is added to the plating bath, causing nickel ions to reduce and deposit on the substrate. Electroless nickel plating offers excellent uniformity, strong adhesion, wear resistance, and corrosion resistance, making it widely used in the surface treatment of electronic components, mechanical parts, and decorative items. This coating also provides good resistance to chemical corrosion, extending the product’s lifespan.
