Review on carburizing and hardening technology of gears in China

Carburizing and hardening process has become a main heat treatment technology in modern gear manufacturing. This technology has got visual progress in China through independent basic technical research and advanced technique introduction, especially technology innovation and equipment renewal in the resent years. However, as the gear design parameters are increasing, which requires higher heat treatment quality, and as the heat treatment technique is developing,various problems in gear heat treatment processes appear in the present production. The present gear carburizing technology was analyzed from the point of strength of gear and physical-metallurgical factors of heat treatment, some suggestions to increase and develop the carburizing and hardening technique of gears in China were proposed.
