摘要: 以酚醛树脂、环氧树脂为粘结剂，采用单一因素考察法，分别考察了ZrO2和Al2O3共2种具有高反射率的耐热填料对高能激光防护涂层性能的影响，分别对其抗高能激光烧蚀性能、耐激光辐照时间、激光辐照前后涂层表面反射率等性能进行了表征，开展了辐照前后涂层表观形貌观察及XRD扫描，从微观角度确定了耐热填料晶型变化情况。结果表明，ZrO2在高能激光辐照过程中具有良好的耐高能激光烧蚀性能，可耐受高能激光辐照功率密度达到2.35 kW/cm2，激光辐照前后涂层表面反射率提高了46.28%。Abstract: With phenolic resin and epoxy resin as binder and the single factor investigation method, the effects of high reflectivity heat-resisting packing materials of ZrO2 and Al2O3 were investigated, respectively. The resistance to high energy laser ablation, holding time to laser ablation and the surface reflectivity before and after the irradiation were characterized. The surface morphologies before and after irradiation were compared by observation and XRD testing to observe the crystal form changes of the heat resistant packing materials.Resultsshowed that ZrO2 had good resistance to high-energy laser ablation with the tolerance of the power density of high-energy laser irradiation up to 2.35 kW/cm2, and that the surface reflectivity increased by 46.28% after laser irradiation.
