The formation of the coating during the deposition of a mechanical mixture of particles of copper, zinc and corundum is accompanied by the predominant diffusion of copper into zinc, the diffusion coefficient has an abnormally high value and is within 0.75- ≈ 2.25x10 -8 cm 2 /s. Analysis of the features of the gas-dynamic spraying of a coating based on a mixture of metal particles and corundum shows the influence of the mechanical action of corundum particles on the diffusion process, in particular copper into zinc. 5.
