This paper presents the results of a study on the high-temperature oxidation characteristics after mechanical and laser removal of TA15 titanium alloy oxide film. The morphology, components, and roughness of the surface were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and laser confocal microscope (OM). The oxide film can be effectively removed with mechanical grinding and laser cleaning, and the oxide film after mechanical grinding is thicker and looser than that of after laser cleaning. The oxide film is principally composed of TiO₂, Ti₂O₃ and TiO. Besides, there is a small amount of aluminum oxide on the surface. The surface after mechanical grinding was rougher than that of after laser cleaning. Thus, this work indicates that laser can not only clean the oxide film completely, but also strengthen the surface, which is a promising way to favor the widespread application of laser cleaning technology.

TA15钛合金机械研磨激光清洗后的高温氧化行为

本文介绍了机械和激光去除 TA15 钛合金氧化膜后高温氧化特性的研究结果。通过扫描电子显微镜 (SEM)、X 射线衍射 (XRD)、X 射线光电子能谱 (XPS) 和激光共聚焦显微镜 (OM) 对表面的形貌、成分和粗糙度进行了表征。机械研磨和激光清洗可以有效去除氧化膜，机械研磨后的氧化膜比激光清洗后的氧化膜更厚更松。氧化膜主要由TiO ₂、Ti ₂ O _{3 组成}和二氧化钛。此外，表面有少量氧化铝。机械研磨后的表面比激光清洗后的表面更粗糙。因此，这项工作表明激光不仅可以彻底清洁氧化膜，而且可以强化表面，这是有利于激光清洁技术广泛应用的一种有前景的方法。
