Sažetak

As modern air engines’ working temperatures are increasing, materials and coatings' hot corrosion resistance characteristics gain significant attention. Hot corrosion is a type of degradation at high temperatures that involves oxidizing or sulphidation of the substrate behind a layer of salt melt deposit, which either causes the development of a thick layer of sulphide scale or the penetration of sulphur via grain boundaries into the matrix to a deeper depth. It may notably change the microstructure, phase composition, and characteristics of the thermally sprayed coating. In recent years, thermally sprayed cermet coatings on steel have been more well-liked as a possible method for enhancing hot corrosion resistance. This review paper qualitatively summarizes the recent development of thermal sprayed coatings to improve hot corrosion performance.
