A quick cooling of coatings for the forming of the electrolyte layers with the given phase composition is widely used. In this work the preliminary heating of the specimens was applied instead of quick cooling technology. The influence of the substrate preliminary heating on the ZrO2 – Y2O3 coatings structure and properties was investigated. The optimal of the spraying of coatings from the Ni and ZrO2 – Y2O3 powders mechanical mix was determined. The research on the coating structure was carried out analysing the application of the optical metallography, scanning microscopy and X-ray method.
