摘要

基于烧蚀气化材料去除机理, 利用高重复频率脉冲激光对低热导率树脂基涂漆的定量去除进行理论及实验研究。研究了二维振镜系统激光清洗扫描方式的选取, 以及脉冲激光作用于材料表面光斑的分布特性。对材料表面的温度变化进行理论仿真后发现, 脉冲间隔对材料温度变化的影响较小。进行了高重复频率脉冲激光烧蚀气化去除低热导率涂漆的实验, 结果表明:作用于涂漆表面的脉冲数与烧蚀气化去除深度线性相关, 从而建立了二者之间的一维线性关系方程。

Abstract

Based on the mechanism of ablation, we study the quantitative removal of low thermal conductivity resin-based paint with high repetition rate pulse laser. The selection of scanning mode of a two-dimensional galvanometer system is studied, as well as the distribution characteristics of laser spots on material surface. The temperature change of material surface is simulated and it is found that the pulse interval has little influence on the material temperature change. The experiments of high repetition rate pulse laser ablating low thermal conductivity paint are carried out. The relation between the pulse number acting on paint surface and the ablation depth is linear, and a linear equation is established.
