In high-temperature environments, this refers to the ability of a material to resist oxidation reactions with oxygen (air), avoiding continuous oxidation corrosion and performance degradation. At high temperatures, an oxide layer readily forms on the material surface; if the oxide film is loose and easily peels off, oxygen continuously penetrates inward, the substrate is continuously consumed, and peeling, holes, and strength reduction occur. Oxidation resistance is used to evaluate the ability of a material to resist oxygen oxidation corrosion at high temperatures. In high-temperature environments, materials readily react with oxygen to form an oxide layer. When the oxide film structure is poor, oxygen continuously intrudes into the substrate, causing material loss and structural degradation. Conducting oxidation resistance evaluation can determine the corrosion rate of materials under long-term high-temperature service and predict the service life of components. Through constant-temperature oxidation and cyclic oxidation tests to measure oxidation weight gain, combined with microscopic analysis of the oxide layer state, oxidation-resistant materials can be screened to prevent components from peeling and strength reduction due to continuous oxidation, ensuring the stable operation of high-temperature equipment.
