采用电解沉积和微波烧结的方法，在MCrAlY基体表面成功制备了YSZ/Al2O3微层压涂层。通过高分辨率场发射 SEM 和 XRD 对所制备的 YSZ/Al2O3 涂层进行了表征。涂层中观察到交替的YSZ和Al2O3层状结构，其相组成为Y2O3稳定的t-ZrO2、α-Al2O3和θ-Al2O3。还进行了空气中 1000°C 的高温循环氧化测试，以研究 MCrAlY 基材上此类涂层的抗氧化和抗剥落性能。结果表明，由于多层密封Al2O3层的结构和设计的层状复合材料结构所带来的良好的高温机械性能，这种涂层不仅表现出优异的抗氧化性，而且在热循环下表现出良好的抗剥落性。
YSZ/Al2O3micro-laminated coatings were successfully prepared on the surface of MCrAlY substrates by means of electrolytic deposition and microwave sintering. The as-prepared YSZ/Al2O3coatings were characterized by high-resolution field emission SEM and XRD. Laminated structures of alternate YSZ and Al2O3layers were observed in the coating with the phase composition of Y2O3stabilized t-ZrO2, α-Al2O3and θ-Al2O3. High-temperature cyclic oxidation test at 1000°C in air was also performed to investigate the oxidation and spallation resistance of such coatings on MCrAlY substrates. The results indicate that such coatings exhibit not only excellent oxidation resistance but also good spallation resistance under thermal cycling due to the structure of multi-sealed Al2O3layers and the preferable high-temperature mechanical properties induced by the designed laminated composite structures, respectively.
