Abstract:
Laser surface cleaning is a promising surface-cleaning technique owing to its numerous benefits, including its noncontact behavior, ease of control, high precision, and no secondary waste generation. However, it cannot prevent airborne nanoparticle emissions during the laser cleaning process. Therefore, the effects of laser-cleaning parameters on airborne nanoparticle generation are analyzed to design potential remediation methods. In this study, the nanoparticles released during the laser cleaning of corroded 304L stainless steel surfaces were investigated. Electrical low-pressure impactor analysis and electron microscopy were conducted to determine how laser parameters influenced the size and amount of emitted nanoparticles. Based on these findings, the feasibility of the filtering emitted nanoparticles using high-efficiency particulate air filters was examined.

激光表面清洁是一种有前途的表面清洁技术,由于其众多的好处,包括它的非接触行为,易于控制,高精度,不会产生二次废物。然而,它不能防止激光清洁过程中空气中的纳米颗粒排放。因此,分析了激光清洗参数对机载纳米粒子生成的影响,以设计潜在的修复方法。在这项研究中,研究了304L不锈钢表面激光清洗过程中释放的纳米颗粒。进行了电低压撞击器分析和电子显微镜检查,以确定激光参数如何影响发射的纳米颗粒的大小和数量。基于这些发现,研究了使用高效微粒空气过滤器过滤排放的纳米颗粒的可行性。
