Characteristics of crevice corrosion: corrosion occurs in the crevice, and the metal outside the slit is protected;
The width of the gap that constitutes crevice corrosion is between 0.025 and 0.1mm;
The materials that make up the crevices are non-particular, and the metal or non-metallic crevices cause crevice corrosion to the metal;
Almost all corrosive media will cause corrosion of metal gaps, and it is easiest to inflate the chloride-containing active anionic solution;
Almost all metals or alloys produce crevice corrosion, which is more serious than blunt metals. (For more latest news, please see "Hardware and Electrical Materials" wjdl.wang to understand)
