选择性激光熔化(SLM)中的后处理操作变得越来越重要,以便能够获得具有最大性能的组件。在这篇论文中,作者提出了与飞秒激光冲击喷丸处理(f-LSP)后获得的微观结构修改有关的第一个结果,脉冲宽度为165 fs,每个脉冲的能量在200-600 μJ之间变化。通过改变能量和扫描参数两者来获得用SLM产生的样品,并且用f-LSP处理的表面与构建方向平行和正交。
Post processing operations in selective laser melting (SLM) are becoming increasingly important to be able to have components with maximum performance. With this paper, the authors present the first results relating to microstructural modifications obtained after a femtosecond laser shock peening treatment (f-LSP) with a pulse duration of 165 fs and energy per pulse varying between 200-600 μJ. The samples produced with SLM were obtained by varying both the energy and scanning parameters and the surfaces treated with f-LSP are both parallel and orthogonal to the build direction.
