Thermal Corrosion Behavior of NiCoCrAlY Coatings Prepared by Different Thermal Spraying Methods

Abstract:

The protection of thermal parts has become one of the most important techniques with the development of high capability and high thrust-weight ratio for advanced aeroengine. In this paper, using the nickel base superalloy as the substrate, the thermal corrosion performances of NiCoCrAlY coatings using different thermal spraying methods, which consisted of high velocity oxy-fuel (HVOF), detonation spraying (DS), atmospheric plasma praying (APS) and low pressure plasma spraying (LPPS), were studied. The thermal oxidation experiments, which consisted of isothermal oxidation and cycling oxidation experiments were performed to character the thermal performances. From the results, it was shown that the NiCoCrAlY coatings prepared by high velocity oxy-fuel method were slight for 100 hours at 1100°C. The surface of the NiCoCrAlY coatings prepared by HVOF had a dense, continued Al₂O₃ oxide layer. Among all the methods to prepare NiCoCrAlY coatings, the method of high velocity oxy-fuel showed excellent performance.
