Category Protective coatings for metals

Technology of chemical nickel plating of products of steel, cast iron and plastic

As a result of its undeniable advantages and specific qualities, chemical nickel plating can be used in automobile manufacturing, instrument engineering and in many other branches of production sector.

The most important among them is the fact that chemical nickel plating has high protective qualities and it is more effective to aggressive environment in comparison with electroless nickel.

The technology provides more qualitative covering of not only the products of metal, cast iron, plastic but of inorganic dielectrics which include ceramics, glass, porcelain, glimmer, ceramized glass and ferrites.

Advantage: offered technology has high effectiveness and quality and is profitable economically
