Nickel plating is a proces at which a layer of nickel is added to the product’s surface. This forms a protective layer which can protect the product against rust and other corrosion.
Electroless nickel plating (electroless or chemical nickel plating) is a chemical dipping process, in which the surface of a product is provided with a nickel-phosphorous layer. This layer has a phosphorus content of about 8%. The phosphorus in the layer makes the product corrosion resistant and also more wear-resistant than pure nickel. The hardness of the nickel-phosphorus layer can be increased to almost 1000 Vickers when a heat treatment is used.
A major advantage of this process in comparison to galvanic nickel plating is an even layer, without buildup on the edges. This can be achieved for both ferrous as well as non-ferrous metals.
Electroless nickel plating is an accurate process with a tolerance of about 2 µm.
Galvanic nickel plating is a process in which the product is nickel plated by means of electrolysis which acts as the cathode. In galvanic nickel plating, layer thickness is not uniform, since it is likely to have buildup on the edges.
MTRC has the facilities to clean/and or package products in our cleanroom (Grade 2,3 and 4 – surface cleanliness, ISO 7)
Providing good quality, in all its aspects, is obvious to MTRC. Good product quality is ensured by a structured process control, but also by a thorough technical and visual inspection of the finished product.
