The method of electron probe micro-analysis was used to analyze the distribution of elements over the diffusion layer obtained by the deposition on copper of gas-thermal coatings involving Al, Ni, Cr, Fe and subsequent heat-treatment. It was established that the penetration depth and concentration of the coating elements attained their maximum values in the case of the presence of an aluminium sub-layer.
