Plating is used within the aerospace sector on a range of components, such as landing gear, axles, and turbine blades. Different surface finishes are used on different components and here we explore some of the most common uses.
What are the most common aerospace surface treatments?
Some of the most commonly used surface treatments within the aerospace sector include anti-corrosion systems, and hard-wearing coatings. You can learn more about the treatments available on the websites of specialists such as //www.poeton.co.uk/about/industries/aerospace-defence/.
Protection against corrosion
Cadmium is often used to provide a corrosion-resistant barrier to things like support lugs and landing gear. As there is no post-baking necessary with this process, any repairs can be made with little-to-no disassembly required. However, cadmium is a hazard to health and therefore many aerospace businesses are looking for alternatives.
Improved wear resistance and hardness
Durability and reliability are key in the aerospace sector and surface finishing can help to deliver additional hardness and wear resistance to numerous components. Nickel or nickel alloys are often used here, as they deliver consistent results that stand the test of time.
Selective anodising
The selective anodising process doesn’t generate any heat, making it a highly versatile option that enables technicians to replace damaged or worn hardcoat without resulting in any dimension loss.
Refurbishment finishings
Nickel is also used to restore and refurbish a range of internal and external components, such as bushing bores and end bell housings. This form of plating can be done to a range of thicknesses without the need to disassemble complex parts.
