我厂轴承零件热处理淬火盐浴采用氯化钠和氯化钾。由于氯化物的大量存在,很容易被吸附在具有氧化膜的金属表面,氧化膜中的氧离子就被氯所代替而破坏了造成锈蚀,加上氰离子半径很小,容易穿过金属表面锈蚀膜层,再与金属层起作用继续锈蚀,容易与已锈蚀的产物起作用,生成溶解的氯化物使锈蚀继续进行,它对金属的破坏作用很大,会导致轴承零件报废或降级。热处理 I plant bearing parts quenching salt bath with sodium chloride and potassium chloride. Due to the large amount of chloride, it is easily adsorbed on the metal surface with oxide film. The oxygen ions in the oxide film are replaced by chlorine to destroy the corrosion. In addition, the cyanide ions have a small radius and easily pass through the surface of the metal Film, and then the role of the metal layer continue to rust, easy to work with the product has been rusted, the formation of dissolved chloride corrosion continued, it is a great damaging effect on the metal will lead to bearing parts scrapped or downgraded.
