How Are Nickel Coatings Used in Aircraft?

Nickel coatings are often used on various parts of aircraft due to its fantastic properties of corrosion resistance and hardness. Needless to say, the Aircraft industry has an ongoing need for nickel plating.

Electroless nickel plating is used in the Aircraft industry to provide:

  • Corrosion resistance at high temperatures to protect airfoil components from erosion and abrasion.
  • Provides a coating that will allow high nickel/chromium alloy parts to be joined by brazing or welding.
  • To repair worn or damaged components so that they can continue to be used rather than scrapped.

Electroless nickel coatings have been used on the following aircraft parts:

  • Bearing journals
  • Servo valves
  • Compressor blades
  • Turbine blades
  • Pistons
  • Engine shafts
  • Engine mounts
  • Landing gear
  • Hydraulic and manifold systems
  • Gyroscope components and optics

The Smart Metal that Remembers its Shape!

As a leading plating and metal finishing company, us have always been fascinated by the many uses of nickel. Nickel really is a very useful metal and it is used in all sorts of everyday items that you wouldn’t expect.

Nickel-titanium shape memory alloy is what is known as a ‘smart metal’. If it is deformed in any way or heated up, it naturally returns to its original shape, or ‘remembers’ it!

Nickel-titanium alloy

This alloy is commonly used for the frames for glasses, the kind that spring back into shape even if you sit on them. Nitinol is the generic name for the family of nickel-titanium alloys.

Nitinol stands for Nickel Titanium Naval Ordnance Laboratory, and in 1961 a researcher at an American Laboratory discovered that this particular alloy has ‘shape memory’.

Although it was a fantastic discovery which has gone on to change the way glasses are made, it was actually come across by accident. During a laboratory management meeting, a badly bent strip of Nitinol was presented to the attendees. An attendee of the meeting picked up the piece of Nitinol and heated it up with his pipe lighter. To the amazement of the people in the room, the strip stretched back to its original shape.

So, whichever way you bend, stretch and pull your frames, they will always return to their original shape!
