“…The main components of the oxide film are Al, Ti and O, and the oxide film consisted of titanium oxides and alumina. Oxygen not only forms oxide film on the surface, but also a small amount of oxygen will also diffuse into the substrate for strong diffusion at a high temperature [6,11,12]. The aluminum content is concentrated on the upper surface for the sample after laser cleaning, which can inhibit the further oxidation of titanium alloy.…”

“…The Al and V can improve oxidation resistance. Soon Yong Park [12] proved Al, Nb and Si to increase the oxidation resistance of Ti-44Al-6Nb-2Cr-0.3Si-0.1C alloy, and Nb, Cr and Si have tended to segregate the oxide scale-matrix interface. Dongjun Wang [13] investigated the oxidation behaviors of the TA15 titanium alloy and TiBw/TA15 composite in the temperature range of 873-1073 K, and TiBw/TA15 composite exhibited a higher oxidation resistance than TA15.…”

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.
