| Summary: | The article considers the issues of the numerical analysis of the temperature distribution in a powder coating based on zirconium dioxide during the laser melting process. The assumption is substantiated that adding 20% nickel-chrome alloy powder to the coating makes it possible to form a frame structure of the coating, which will increase the strength of the resulting heat-protective coating. Calculation graphs characterizing the temperature and time of propagation of the metal powder melt front along the thickness of the coating are considered. Attention is paid to achieving the melt boundary of the chromium sublayer, which will provide increased adhesive strength of the applied coating. Based on the study, the prospects of the proposed technology for applying a coating to protect against oxidation of carbon composites from the effects of high-speed gas flows, especially for coating large surfaces, are noted. |
