Abstract Carburization-quenching process of aerongine has been researched. Vacuum-carburizing process parameters
has been adjusted. The results showed that the depth of the surface coating was 0.5 mm. Step quenching, loading mode, and
stress-relief method has been improved. The part has high hardness and small deformation after carburizing and quenching,
through the assessment of the aeroengine 150h lasting. The prospect of engineering application for carburization-quenching
process of thin-wall hollow shaft was very good.
