Electroless Nickel Plating and Its Use in Aerospace Applications

Electroless nickel has many fantastic qualities which make it perfect for use in the aerospace industry. Below are some of the components used in the aerospace industry that electroless nickel is commonly use to plate.

Turbine blades and compressor blades

Turbine blades and compressor blades are parts of aircraft engines frequently exposed to highly corrosive environments. Electroless nickel is extremely corrosion resistant, making it favourable for this type of use.

Engineers working in the aerospace industry often use aluminium because of its light weight and density. An electroless nickel coating compliments the properties of aluminium by adding solderability, corrosion protection, wear resistance and hardness.

Piston Heads

The combination of electroless nickel and aluminium is often used to make piston heads. Electroless nickel is an effective coating because it prevents wear, and therefore increases the life of the piston. Aluminium is effective because it is so lightweight, meaning that the piston is able to work better.

Aircraft shafts

Electroless nickel is often used to plate the main shafts of air craft engines because it provides an excellent bearing surface. Typically, during air craft maintenance, rebuilding the shaft may be necessary. But with electroless nickel, the surface can be stripped off and re-plated to the thickness needed instead of buying new components, therefore saving money. This technique is also used when reconditioning rear compressor hub sleeves and bearing liners.
