Electroless nickel plating

steelISO 9227-NSShigh phosphorus

Electroless nickel plating is an electroless process in which a deposition that is true to the contours takes place on the entire surface. Even with complex shaped workpieces and in interior areas, an even distribution of layer thickness can be guaranteed. The nickel-phosphorus layer is characterized by hardness, wear resistance and very good corrosion resistance. In addition, the coating properties, such as magnetic/non-magnetic, can be controlled via the phosphorus content. For this purpose, we offer the electroless nickel processes Mid-Phos and High-Phos. Advantages of coating without external current In comparison with electrolytic processes such as hard chrome plating, for example, the electroless process has a decisive advantage: the uniform distribution of the coating thickness. Electroless nickel plating is an autocatalytic reduction process. The electrons required for deposition are not supplied by an external power source as in galvanic processes, but are generated by the chemical reaction of a reducing agent within the electrolyte. As a result, the same deposition conditions prevail on the entire surface of the component, resulting in a uniform layer structure. Even with complex component geometries, a uniform layer thickness distribution at corners, edges and inner surfaces can be guaranteed.
