Abstract
Ceramic-based high-temperature resistant coatings have a wide range of applications in the field of surface protection of high-temperature components, and their excellent antioxidant, thermal shock, and thermal stability properties are essential to enhance the service life of high-temperature components. This paper reviews the latest research progress of ceramic-based high-temperature coatings, focusing on the preparation process, performance characterization, and application effects of typical systems such as ZrB2-based ultra-high-temperature ceramic coatings, high-temperature antioxidant coatings on the surface of carbonaceous materials, and zirconia nanocomposite ceramic coatings. Through thermodynamic calculations, experimental tests, and microstructure analysis, the intrinsic correlation between the coating material composition, preparation process and antioxidant performance, thermal shock performance, and thermal expansion coefficient is revealed. The study shows that reasonable material selection, optimized preparation process, and composite structure design can significantly improve the comprehensive performance of ceramic-based high-temperature resistant coatings and provide a strong guarantee for the reliable operation of high-temperature components.
