Where high-temperature oxidation and hot corrosion-resistant surface or bond coat required, MCrAlY thermal spray coating is recommended.
MCrAlY thermal spray coatings are used in the hottest sections of gas turbine engines and other high-temperature, corrosive environments. They can be used alone as an anti-corrosion coating or as a bond coat to improve the performance of Thermal Barrier Coating (TBC) systems or ceramic abradable coating systems.
MCrAlY Coatings are well established as an important technology for the manufacture of aero engine and industrial turbines. High turbine combustion temperatures are required for good engine efficiency and some environmental reasons.
MCrAlY where M can be Co, Ni, or Co/Ni. These coatings are widely used in first and second stage turbine blades and nozzle guide vanes, where they may be used as corrosion-resistant layers or as bond-coats for use with thermal barrier coatings(TBC).
