| 摘 要： | 激光清洗在再制造行业、微机电系统（MEMS）和超精密加工行业具有重要的应用前景，飞机蒙皮激光脱漆技术是激光清洗技术中的一个重要分支。利用10.6 m的高重复频率CO2激光器对飞机蒙皮（LY12铝合金板材）上的90 m厚的双层复合油漆层进行去除。研究结果表明，通过选择合适的扫描间距、激光功率密度及扫描次数，成功地将飞机蒙皮表面的两层油漆层完全去除，通过对比试验测试飞机蒙皮在激光除漆前后的抗拉强度、屈服强度、维氏硬度以及粗糙度等力学性能，发现激光除漆未损伤基底且未改变其力学性能。该种除漆方式较传统除漆方式具有环保无接触、效率高、参数可控以及维护成本低等优点，为在其他领域应用开拓新的方向。

| Abstract: | Laser cleaning technology, which is environment-friendly, has a wide range of application prospects in remanufacturing, micro-mechanical system (MEMS) and ultra-precision machining. Laser paint removing of aircraft surface is one of the important branches of the technology of laser cleaning. A high repetition frequency CO2 laser, with 10.6 m wavelength, was used to remove paint, which was double composite paint layer with thickness of 90 m, from aircraft surface (LY12 aluminum plate). It is shown that totally removed paint stripping and undamaged surface can be reached with selecting appropriate laser power density, scanning distance, and scanning time, the double composite paint layer on aircraft surface can be removed totally, the effect of paint removing on the tensile strength, yield strength, Vickers hardness and roughness of the substrate is studied by the method of experimental contrast. It is found that the mechanical properties of the aircraft surface did not change after the treatment of laser paint removing. Aircraft laser paint removing has more predominance than traditional methods, such as environmental protection without contact, high efficiency, parameters controlling, and low maintenance cost and so on, it develops new directions for applications in other fields. |
