Electrolytic Nickel Plating

Electrolytic Nickel plating is traditionally used to improve a part’s wear, abrasion and corrosion resistance — although this coating is commonly seen as a solution for the repair of components.

Techmetals provides this finish to accommodate our clients in industries such as printing, defense and oil and gas to name a few.

Electrolytic Nickel Plating

Electrolytic Nickel plating involves bonding the substrate with the Nickel coating through an induced electric charge. An external DC current is used for deposition of the coating, which differs from other forms of electroless plating applications. This “combination” occurs through a chemical reaction between the coating and a substrate.

Electrolytic Nickel is typically desired due to its conductivity properties, combined with exceptional wear resistance. Plating with this material also provides a diffusion barrier for a tin, silver or gold outer layer — preventing unwanted solid state diffusion between the two coatings.

Benefits of Electrolytic:

  • Machinable deposit used in the repair of components eliminating the remaking  costs.
  • Plating for a range of base materials
  • Custom masking services

tm109An electrolytic nickel deposit of the purest nickel providing a soft ductile coating of 20 Rockwell hardness.

It has outstanding corrosion resistance, solderability, magnetic characteristics and it resists oxidation at high temperatures. Coating thickness up to .250” are not uncommon.

Techmetals currently handles large production and sized parts with a 5-ton capacity and tanks up to 10-feet in length.

TM 109 is ideal when a pure, stress free, machinable and corrosion resistant deposit is required.
