In the present work, the influence of technological parameters of detonation sputtering, in particular the degree of barrel filling, on the properties of chromium oxide (Cr2O3) coatings was investigated. Coatings were obtained under different sputtering conditions and analyzed comprehensively using X-ray phase analysis, optical and electron microscopy, and measurements of microhardness, porosity, and tribological characteristics. The results showed that the degree of barrel filling significantly affects the microstructure, thickness, porosity, and mechanical properties of the coatings. The sample obtained at 58% barrel filling showed the lowest porosity (0.01%), uniform distribution of chromium oxide, and the best adhesion, which makes it possible to consider this mode as optimal for the formation of wear-resistant coatings by detonation spraying.
