摘要:Titanium alloys have been widely used in the aerospace industry because of their low density, high specific strength and high temperature resistance. The high reflectivity of titanium alloy, however, hinders its practical applications. It is therefore of great importance to improve the anti-reflection performance of the titanium alloy surface. The strong trapping properties of the metal surface can be achieved by constructing a rough microstructure so that enhances its absorption of incident light. Nevertheless, traditional processing methods make it difficult to construct such microstructures due to the discontinuity of the built microstructures, laser processing methods are often used in this regard. In this paper, the surface of titanium alloy was processed by nanosecond laser, and the reflectivity of the alloy sample was measured by a microscopic angle resolution spectrometer. In addition, confocal laser scanning microscope(CLSM or LCSM), scanning electron microscope(SEM) and energy spectrum analyzer(EDS) were used to observe the morphology of the microstructure in two-dimensional and three-dimensional manner, and conduct elemental composition analysis. The effects of ultrasonic treatments on the reflective properties of laser-treated titanium alloy reflective surfaces were investigated using different cleaning conditions. The results show that the reflectivity of titanium alloy microstructures changes significantly in the visible and near-infrared regions under different ultrasonic cleaning conditions.
