Abstract:Si-based ceramics have high melting points, high stability and excellent oxidation resistance. Among them, the good interfacial bonding ability makes SiC-based coatings widely used in aerospace and other industrial fields. The paper introduces the more advanced SiC-based coating preparation process, outlines the research progress of this type of coating for the antioxidant property of the material, and puts forward an outlook on the further research direction of SiC-based ceramic coatings.
