摘要: 为了研究脉冲激光去除金属表面漆膜的过程,采用有限元法建立模型,模拟了喷有漆膜的不锈钢样品表面在移动脉冲激光作用下的温度场,研究了不同时刻漆膜表面的温度场分布以及激光参量对漆膜表面温度场的影响,并做了相关对比实验。结果表明,漆膜表面温度随激光源的移动而变化,温度场呈现带尾的彗星状;漆膜表面的温度随激光能流密度和激光重复率的增加而线性增加,随着扫描速率的增加而指数递减;激光能流密度和激光重复率越大而激光扫描速率越小时,激光除漆效率越高;温度的累积效应可以提高除漆的效率。该结果可以为实际激光除漆过程中激光参量的选取提供参考。

Abstract: In order to analyze the process of laser removal of paint on metal surface, the model was established by using finite element method (FEM). Temperature distribution on stainless steel surface with paint film irradiated by moving laser was simulated. The relative and comparative experiment was done. The results show that, temperature of paint film changes with the movement of laser source. Temperature distribution has a rendering tail like comet-shape. The peak temperature of paint film increases linearly with the increase of laser fluence and laser repetition rate, and decreases exponentially with the increase of scanning rate. The higher the laser fluence and repetition rate, the higher the paint removal efficiency. Cumulative effect of temperature can improve the efficiency of removing paint. The results can give references to select laser parameters in the process of laser paint removal.
