Abstract:Heat treatment, as the basis and generic technology in the research of advanced aero-engine, is a critical
factor in the serviceability of the aero-engine components. Based on the researches and practices of heat treatment in the
field in recent years, this paper first gives a general review of the status of advanced heat treatment, and then puts emphasis
on the analysis and discussion of the appliance of vacuum heat-treatment, chemical heat-treatment and special heattreatment
on the manufacturing of key components on blade, disk, gear, bearing and rotor. At the end of the paper, it looks
forward into the future research and development of heat treatment in the field of aero-engine in our country.
