Study of heat-resistant coatings of the VSDP-11, TiAl, AlCr, AlY systems

Abstract

The article describes the study of technologies for the deposition of heat-resistant coatings based on three different systems – TiAl, AlCr, AlY and VSDP-11. Coatings were applied onto samples made of the high-temperature alloy ZhS6K-VI. Samples with the coatings were subjected to diffusion annealing and high-temperature tests, and were studied using scanning electron microscopy, energy dispersive and X-ray diffraction analysis. The results of the study showed that the developed technology makes it possible to produce uniform coatings that enable increasing the heat resistance of blades made of the high-temperature alloy, without destruction of the coatings as a result of high-temperature oxidation. The obtained results indicate the applicability of the coatings in real blade production conditions. doi 10.54708/19926502_2024_283105129
