Laser stripping paint was studied with a pulsed laser in our work, which focuses on the effect of the process parameters, and on the understanding of the mechanism of this type of technology. Regarding the characterization of the stripping surface, surface morphology and surface roughness had been determined by a three-dimensional profilometer. The orthogonal optimization experiment had been carried out to optimize the process parameters. Combining experiments with simulation calculation, the laser stripping paint mechanisms were thoroughly investigated. Stripping paint with a pulsed laser is dominated by the thermal combustion effect, thermal stress and thermal vibration effect, laser plasma shock effect.

我们在工作中采用脉冲激光对激光脱漆进行了研究，重点研究了工艺参数的影响，以及对此类技术机理的理解。关于剥离表面的表征，表面形态和表面粗糙度已通过三维轮廓仪确定。进行了正交优化实验以优化工艺参数。结合实验与模拟计算，对激光脱漆机理进行了深入研究。脉冲激光脱漆主要受热燃烧效应、热应力和热振动效应、激光等离子冲击效应的影响。
