Abstract In this study, multi-chamber detonation sprayer (MCDS) was applied for deposition of NiCoCrAlY powder coatings (60-65 mm thick) on nickel base superalloy JS6U (Russia). Powder RPCoCr27Al7Si3Y was used to deposit of a coating. The coating microstructures and phase compositions were characterized using SEM, OM and XRD techniques. Measurement of the microhardness of samples was done with a micro-hardness tester DM – 8B using a Vickers’s indenter with load on of 0.01 N. It was established that MCDS has provided the conditions for formation of a dense layer with porosity below 1% and microhardness of 1100 ± 250 HV0.1.
