Abstract
The paper analyzes the contemporary knowledge by the blasting as the optimal technology for creation of the substrate surface. At the same time, the study support the evaluation of the character of the blasted surface related to the adhesion of the post-applied coatings. Moreover, the study deals with the creation and the characteristics of the ceramic oxide coatings especially used in the conditions of the thermo cyclic loading. In the end of the study, there is analysis of structural changes and crack propagation in the process of the thermal loading at the coatings based on Al2O3 and ZrSiO4, which indicates the convenience of investigated coatings for concrete loading conditions.
