Abstract: Historical progress of wind power components heat treatment technology in China was reviewed, from the aspects of technical system, material choosing, equipment and instrument, quenching medium and test technology over the past 40 years. The research status of gear strength and the key heat treatment technical indicators such as chemical composition, hardenability, banding, purity, case depth design were analyzed. In addition, the gap between domestic and international advanced level was also analysed. The technical route in future should be focus on 5 aspects including strength improvement, raw material enhancement, promotion of green and energy-efficient medium, automatic and high-efficiency equipment application, and virtual heat treatment using. The key technologies of full face width induction hardening, pure water hardening, high-efficiency shot peening, high-temperature carburizing, continuous equipment and virtual heat treatment will lead the wind power gear heat treatment process and the equipment development trend of green, intelligence, and precision.

Key words: wind power gear, material, heat treatment equipment, heat treatment process
