However, modern QPQ technology is a surface modification technology, and its actual process mainly includes salt bath composite treatment, including salt bath nitriding and salt bath oxidation.

[0003] During the salt bath nitriding and oxidation of QPQ, the high-temperature salt bath will produce water vapor containing salt and impurities. These water mists have high temperature and contain impurities and salt particles inside. Long-term exposure of workers to the environment containing salt mist may cause respiratory diseases and other health problems for operators.
