摘　　要：为提高激光冲击效果,并提高生产效率,分别使用改进配方后的黑漆涂层配合水约束层和柔性贴膜技术对奥氏体不锈钢进行激光冲击试验,对冲击后的硬度和残余压应力进行分析比较。结果表明改进后的吸收层有更好的防护能力,且与水约束层配合可连续冲击,柔性贴膜技术提高了约束效果。In order to improve the effect of laser shocking and increasing efficiency of industry production, the laser shock experiment to the austenitic stainless steel had been carried out. The improved black paint cooperating with water confinement layer and flexible coating was used respectively. It was found that improved black paint combined with water confinement layer will adapt to the demand of continuous laser shock processing from the analysis of hardness and compressive stress after laser shocking. The flexible coating based on macromolecule materials can become a better energy conversion body.
