| 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. |
