Reflective laser protective coating based on plasma spraying

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.
