In this study, a multi-chamber detonation sprayer is used to deposit cermet coatings on flat specimens of corrosion-resistant steel. It is shown that the sprayer provided conditions for the formation of dense WC-CoCr, CrC-NiCr, and CrC-TaC-NiCr layers, ranging in thickness from 80-375 μm, with low porosity, high microhardness, and low wear rates.
