[0002] Some equipment and pipelines in nuclear power plants may come into contact with salt water, especially in the seawater circulation cooling system of coastal nuclear power plants. Seawater (containing salt) can corrode the equipment. Chloride ions and other components in salt water are highly corrosive. They can destroy the protective film on the metal surface, causing pitting and crevice corrosion of the metal, accelerating equipment aging and damage, and affecting the normal operation and safety of nuclear power plants. In order to study the impact of salt water corrosion on workpieces and explore the impact of salt water immersion on workpiece quality, many scholars at home and abroad have conducted salt water immersion tests in laboratories.
