摘要:本文首先介绍了 武器在未来战争中的突出地位和发展现状，阐明了高能 束与目标材料相互作用时的热效应毁伤机理；总结了基于等离子喷涂的反射型 防护涂层的研究进展，包括等离子喷涂金属涂层和陶瓷涂层的研究进展、以及各自的技术特点和防护效果，为高能 防护领域的研究提供了借鉴。研究结果表明，控制金属涂层在 辐照过程中的氧化现象能有效地提高涂层的 防护性能，同时具有优异反射性能的新型陶瓷涂层在高能 防护领域中有较好的发展前景。Abstract:This paper first introduces the significant status and state-of-the-art of laser weapon in future war, discusses the thermal damage mechanism of high-energy laser beam interacting with target materials, and summarizes the research progress of reflective laser protective coating based on plasma spraying, including plasma-sprayed metallic and ceramic coatings. In addition, their individual technical characteristics and protecting performance are also analyzed, which provide a reference in research field of high-energy laser protection. The result of research shows that the control of oxidation for the metallic coating in the process of laser irradiation can effectively improve the laser protective performance. Moreover, we believe that the new ceramic coatings with excellent reflectivity will have a better development prospects in the field of high-energy laser protection.
