Thermally Sprayed Coating Systems for Surface Protection and Clearance ControlApplications in AERO Engines

摘要

The principal current and new thermal spray coating processes used forcompressor, combustion chamber and turbine applications in aircraft engines are described with particular reference to high velocity combustion and plasma spraying techniques. The uses of coatings for wear and erosion resistance, oxidation and corrosion control, thermal barrier applications and gas path sealing (clearance) are discussed.
