Abstract The structure of the gas-dynamic coating based on the mixture of copper, zinc and corundum powders was analyzed using the methods of X-ray diffraction phase and micro X-ray spectral analysis. The influence on the properties of the technological modes structure of spraying, such as the air flow temperature and the layers overlap coefficient was identified. It was revealed that during spraying, the deformation and grinding of the starting metals particles occurs. The overlapping amount of the applied coating layers and the surface heating temperature during the spraying process significantly affects the content and size of metal elements and the resulting phases, the areas of coherent particles dispersion in the coating, their lattice constant and microstrains. The dependences revealed made it possible to vary the specific properties of the coating structure, which made it possible to significantly increase the modified products operational characteristics. © 2022 The Authors.
