在本文中，我们报告的竞争，在金属表面硬化之间的飞秒冲击喷丸一方面，形成激光诱导周期性表面结构（LIPSS）和表面氧化的另一方面。不锈钢AISI 316由于飞秒激光烧蚀引起的冲击载荷的喷丸被成功地证明。然而，对于某些范围的工艺参数，表面侵蚀由于LIPSS和氧化似乎占主导地位的喷丸效果。讨论了提高喷丸效率的策略。(C)2017爱思唯尔B.V.保留所有权利。
In this paper we report on the competition in metal surface hardening between the femtosecond shock peening on the one hand, and formation of laser-induced periodic surface structures (LIPSS) and surface oxidation on the other hand. Peening of the stainless steel AISI 316 due to shock loading induced by femtosecond laser ablation was successfully demonstrated. However, for some range of processing parameters, surface erosion due to LIPSS and oxidation seems to dominate over the peening effect. Strategies to increase the peening efficiency are discussed.
