Nickel plating

Nickel plating process at Electris Coating Systems

Nickel plating is an electroplating process that is used in many industries, especially in the electric power industry. Its purpose is to improve the parameters of the surface to be treated. A layer of nickel, applied to a component, increases electrical conductivity improves protection against corrosion, but also improves the strength and aesthetic properties of the electroplated object.

At Electris Coating Systems, thanks to dedicated, advanced technologies, the nickel plating process is performed on copper alloy parts and specific and aluminum alloys. 
We offer nickel plating thicknesses as low as 1 μm to 50 μm. Our processes allow us to galvanise components with a maximum length of 2100 mm.

What does nickel electroplating consist of?

Depending on the geometry and size of the components, they are placed in the plating bath on special racks or in dedicated barrels.  The components undergoing this process are first carefully prepared - thoroughly cleaned and degreased, and then they are subjected to etching and decapping (removal of oxides and rust from the surface of the workpiece). Once the surface of the products is well cleaned and rinsed, the components are immersed in baths of electrolyte containing nickel salts. By introducing an electric current, the nickel ion is reduced and deposited on the copper or aluminium surface. The thickness of the nickel layer depends on the coating time of the parts and the electric current density used.

Advantages of the nickel plating process

  • Higher electrical conductivity - thanks to the excellent conductive properties of nickel, the components subjected to this process are ideal for the electric power industry. They not only ensure electrical stability, but also minimize energy losses.
  • High resistance to corrosion and oxidation
  • Good thermal conductivity and resistance to high temperatures
  • Hardening of coated surfaces - nickel is characterized by high hardness and is resistant to abrasion, which is beneficial for components exposed to high mechanical loads.
  • Excellent bond strength to the base metal - electrolytic nickel plating ensures strong adhesion to coated surfaces.
  • Visual and aesthetic improvement of the parts treated - electrolytic nickel plating gives the metal surface an elegant, shiny appearance.
  • Solderability and weldability - further processing of the electrolytically nickel-plated component, such as: soldering or welding, is very easy.
