Aircraft Engine Parts
Aircraft engine parts require high credibility and efficiency so these are made of expensive nickel/cobalt super alloy and titanium alloy. Various protective coatings are applied on the aircraft engine parts to overcome material limit and enhance engine performance. Protective coating technologies in aircraft engine industry have been one of the core technology for advanced aerospace industry.

SKL is applying various kinds of coatings on aircraft engine parts; wear resistant coatings using carbides to improve service life, diffusion coatings for high temperature corrosion resistance of turbine parts, thermal barrier coatings to protect parts from high temperature combustion gas, and aluminum-ceramic inorganic coatings for corrosion resistance of compressor parts. SKL is applying these coatings under the process qualification of aircraft engine OEMs such as General Electric, Pratt & Whitney, Rolls-Royce, and Honeywell.
