The range of thermal spraying processes available for the deposition of surface coatings for compressor, combustion chamber and turbine section components in aero engines are described, and typical coating applications discussed. Combustion flame, arc wire, high velocity combustion and plasma spraying techniques are described, and coatings for wear, oxidation and corrosion resistance, clearance control and thermal barrier applications are discussed.read more

Tribological behaviour at various temperatures of WC-Co coatings prepared using different thermal spraying techniques
TL;DR: In this article, the tribological performance of WC-12Co coatings prepared via air plasma spraying, low pressure plasma spraying (LPPS) and high-velocity air-fuel spraying (HVAF) at temperatures ranging from room temperature (RT, ~25°C) to 650°C was investigated.
