陶瓷涂层加固铝合金薄板的抗激光性能测试

针对铝合金基材设计了ZrO2陶瓷涂层, 采用976 nm连续波激光对样品的抗激光性能进行了测试。基材厚度为2.5 mm, 涂层厚度为0.3 mm, 实验测试时样品前表面加载了0.3 Ma切向空气流。记录了辐照区域后表面测点的温度变化情况, 测量了未辐照区与辐照区的反射率谱, 并进行了XPS成分分析。结果表明: 平均功率密度700 W/cm2的激光辐照60 s样品没有熔化; 辐照区域颜色变白, 对近红外光的反射率变大。颜色变白的原因可能是涂层表面沾染的含碳化合物在激光辐照过程中被热解或气化, 这与XPS检测结果相一致。

Abstract

ZrO2 ceramic coating was designed for aluminum alloy plates and their anti-laser performance was tested using 976 nm CW laser. The alloy substrate is 2.5 mm thick and the coating is 0.3 mm thick. In the tests the plates were subjected to 0.3 Ma tangential airflow. Temperature of the rear surface was recorded with thermocouples. Spectral reflectance of unirradiated area and irradiated area was measured respectively, and XPS analysis was done to investigate the change of elemental composition in the coating induced by laser irradiation. The experimental results show that, the sample could withstand 60 s irradiation by 976 nm CW laser with power density up to 700 W/cm2, and that the color of irradiated area turns white from offwhite, and that the reflectance to near-infrared light increases. The change in color may be the result of pyrolysis or gasification of carbon-containing compounds during laser irradiation, which is consistent with the results of XPS analysis.tangential flow
