We are offering Electroless Nickel Coating Services. The most widespread methods of nickel coating are the electrolytic and chemical methods. Nickel plating is most frequently performed by the dull electrolytic method. Sulfuric-acid electrolytes are the most thoroughly studied and s nickel-plating media. ight nickel plating is achieved by the addition of luster-forming agents to the electrolyte. The electrolytic coatings have some porosity, which depends on the degree of care exercised in the preparation of the substrate surface and on the thickness of the coating. Corrosion protection requires a complete absence of pores; therefore, copper plating is performed first or multilayer coatings are apped, which are more reable than single-layer coatings of equal thickness (steel parts are frequently coated sequentially with copper, nickel, and chromium).
