摘要：

The influence of mechanical processing of CuAl10Fe3Mn2 bronze particles with different energy input intensities on the process of deposition of coatings by the method of cold spraying and the properties of these coatings is studied. It is shown that the deposition efficiency varies depending on the microhardness and porosity of deposited particles. The increase in the porosity (from 2 to 8%) of the resultant coatings for different regimes and intensities of mechanical processing of deposited particles is explained. It is found that the size of the coherent scattering region, material microhardness, and roughness of coatings obtained from the mechanically processed powder have similar values regardless of the intensity of energy input by milling bodies to the processed material.
