In the process of gear manufacturing, carburizing heat treatment is a key step in improving surface hardness and wear resistance. However, if there are surface non martensitic structures (non martensite) and excessive internal oxidation after carburizing, the service life of the gear will be greatly reduced, and even early rapid wear may occur, seriously affecting the reliability and safety of the transmission system.
