This study focuses on the analysis of modern technologies for applying ceramic coatings to titanium alloys to enhance their performance characteristics, particularly for aerospace applications. The article examines key methods and technologies, such as plasma spraying, micro-arc oxidation, electron beam processing, as well as combined and multilayer coatings. Special attention is given to the parameters of plasma spraying that influence the quality and durability of coatings. The research methodology includes theoretical analysis, experimental studies, and comparative evaluation of various coating application technologies, along with the systematization of optimal parameters that improve the operational properties of titanium alloys. The prospects of applying these technologies in extreme loads and aggressive environments are also considered. The results show that plasma spraying, micro-arc oxidation, and combined treatment methods significantly improve the corrosion resistance, wear resistance, and thermal stability of titanium alloys. The greatest effect is achieved by optimizing the spraying parameters, such as plasma temperature, powder feed rate, and substrate distance, which enable the formation of coatings with minimal porosity and high adhesion. In conclusion, the study highlights the importance of modern coating technologies in enhancing the performance characteristics of titanium alloys in critical industries such as aerospace, medical, and energy sectors. Further research should focus on overcoming technological limitations, reducing costs, and adapting methods to industry-specific requirements.

The research was conducted with funding from a grant from the Russian Scientific Foundation № 24-79-10178, https://rscf.ru/project/24-79-10178/.
