NICKEL PLATING CHEMICALS

 

 

Nickel coatings are used in industry for corrosion protection of steel and non-ferrous metals to improve the wear resistance of surfaces exposed to friction. Nickel plating are cathode toward iron and can provide protection only if no pore therein. Therefore, the steel is first coated with a layer of copper (25-35 mm), and then nickel (10 - 15 mkm). Sulfate-chloride electrolytes are the most widely used. Among electrolytes with additives derived from butynediol fine-grained, supple, smooth brighting coatings are deposited. The main disadvantage of the coating - a small resistance to corrosion caused by sulfur inclusions. This can be avoided by applying two- or three-layer coatings. Increased resistance differ composite nickel coatings containing fine particles of dielectric - kaolin, carbides and others.

Main component of chemical agent for nickel plating is nickel sulphate, that is a crystalline substance of emerald green or turquoise color, water-soluble, ventilating in air. This is one of the types of nickel salts. Nickel sulfate is a highly toxic substance, so when you work with it you must follow the rules for handling hazardous substances. Chemical formula: NiSO4•7H2O.

nickel sulfate, nickel vitriol

The use of nickel sulfate (nickel sulfate heptahydrate, nickel sulphate). Today, nickel sulfate is in demand. In most cases it is used for nickel electroplating of products and metals. It is also used for the manufacture of batteries, catalysts, ferrites, in electronic and electrical industries, in metallurgy and for making alloys. Nickel is widely used in perfumery, fat and chemical industry as a reagent.
