| Abstract: | For 18Cr2Ni4WA steel gear,three kinds of shot peening technology were researched.The residual stress and distribution,the retained austenite content and distribution,the microstructure and distribution,the microhardness and distribution of shoting peening layer and the roughness of shot peening surface were analyzed and tested.The optimized shot peening technology of 0.05Amm steel shot and 0.18Amm ceramic shot was acquired,which provided the technical data for guiding the production. |
