Erosion is a kind of destructive corrosion caused by chemical or electrochemical reaction between metal and nearby environment. Metal erosion is a natural tendency. The direct and indirect losses caused by erosion to metal materials are enormous. Erosion can also cause catastrophic breakage of equipment. Safety is the first consideration in the design and manufacture of nuclear power equipment and nuclear waste disposal equipment. The erosion of the nuclear industry is increasingly causing scientists to face up to and become an important topic. Erosion causes the material in the engineering measures to run, run, drop, leak and so on will also cause environmental pollution, affect the human ecological environment.
