纳秒脉冲激光清洗扫描速度对tc4钛合金表面氧化膜清洗质量的影响

Abstract

Objective TC4 titanium alloys have excellent overall performance and are widely used in the manufacture of key components for aerospace and military hardware. However, the oxide film on the surface can adversely affect its formation and performance, which results in porosity in the weld, reduced mechanical properties, reduced electrical conductivity, and weakened bonding of the plating or coating with the substrate. Therefore, the oxide film must be removed from the titanium alloy. Traditional methods for cleaning the oxide film on the surface of titanium alloys have many limitations.However, laser cleaning technology compensates for the shortcomings of traditional cleaning approaches with features such as being green, being efficient, and causing low damage. Several studies have discussed the influence of laser energy density on the cleaning effect. In this study, the effects of scanning speed on the cleaning effect of the oxide film on TC4 titanium alloy surfaces are studied. The results can help optimize the laser cleaning process and improve the cleaning quality and efficiency of titanium alloys.
