Electroless Nickel Coating

Electroless Nickel Plating

Electroless plating is a process which uses an auto-catalytic chemical reaction to deposit

a coating onto a wide range of substrates.

Electroless nickel becomes a uniform, hard and highly corrosion and wear resistance

surface. Because there is no current involved in the deposition reaction.

The deposit is uniform and eliminating the need for finish grinding in most cases.

The phosphorus content gives a natural lubricity, which helps to minimize heat buildup

and reduces scoring and galling and which can be very useful for applications such as

plastic molding.

Phosphorous content: -

High, Mid and Low

Type Low Phosphorus Mid Phosphorus High Phosphorus

% Phosphorus 3-5 % 6-9 % 10-13%

As plated hardness 700 Hv 550 Hv 500 Hv

Advantages of coatings:-

Electroless nickel plating process become less porous than electroplating and control

dimensional tolerances.

Even and uniform film thickness even down, deep, bores and at corners and edges.

Due to precise thickness and uniformity, minimize extra cost and work of grinding,

polishing and lapping.

Helps to prevent downtime, improve operational efficiency and enhances equipment

durability.

Coating Properties: -

Corrosion Resistance

Homogeneous & Uniform Deposit (i.e. all over, on corners, IDs and ODs)

Exceptional lubricity

Application of coatings:-

Valves, Pumps, Spines and Gears, Hydraulic Pistons, Mould and Extruders, Cutting

Knives, Housings, Fastners & Couplings, Fuel Connectors, Medical Equipment.
