摘　　要：对0Cr16Ni5Mo1马氏体不锈钢进行不同工艺的表面喷丸处理后,采用X射线应力分析和衍射分析方法研究了喷丸工艺对试样表面粗糙度、残余应力、衍射半高宽、残余奥氏体含量和显微硬度的影响。结果表明:经钢丸强力喷丸+玻璃/陶瓷丸喷丸的复合喷丸工艺处理后,试样表面粗糙度低,表面残余压应力大且分布均匀,残余压应力层深在100μm以上,衍射半高宽、残余奥氏体含量变化明显,表面硬度显著提升。The effects of shot peening on the surface roughness,residual stress,diffraction half-height width,residue stress and microhardness of 0 Cr16 Ni5 Mo1 martensitic stainless steel were studied by X-ray stress analysis and diffraction analysis.The results show that after composite shot peening process of steel shot-peening+glass/ceramic micro-shot peening,the surface roughness of the sample was low,the residual compressive stress was high and evenly distributed,the depth of residual compressive stress layer was more than 100μm,the diffraction half height and width,retained austenite content changed obviously,and the surface hardness increased significantly.
