摘要 采用电泳沉积技术在喷丸处理和未处理的Inconel600 高温合金基体表面制备YSZ/(Ni,Al)热障复合涂层,然后进行真空烧结.使用X 射线衍射、扫描电子显微镜和电子探针能谱仪分析复合涂层的组成和相变,分析和讨论基体喷丸处理后的YSZ/(Ni,Al)热障复合涂层的显微组织结构和性能之间的关系.结果显示,基体喷丸处理后的YSZ/(Ni,Al)热障复合涂层在1100℃ 等温氧化100 h 后的结合强度和抗氧化增重分别是3.3 N 和0.00817 mg/cm^2,而基体未处理的YSZ/(Ni,Al)热障复合涂层的结合强度和抗氧化增重分别为2.6 N 和0.00559 mg/cm^2.在能谱分析得出喷丸处理的涂层在等温氧化后出现明显的铬元素从基体向涂层扩散.基体喷丸处理后的YSZ/(Ni,Al)热障复合涂层具有更优异的结合性能和抗高温氧化性能. YSZ/(Ni, Al) composite coatings were deposited on Inconel600 superalloy with ball peening (BP) and without (non BP)treatment using the electrophoretic deposition (EPD) technique, followed by vacuum sintering method. The structures and phaseevolution of the coatings were studied with X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersivespectrometry (EDS). The relation between microstructures and properties of the BPs-coated samples was discussed. The results showthat the adhesion strength and gain mass of the BPs-coated samples with isothermal oxidation at 1100℃ for 100 h are 3.3 N and0.00817 mg/cm^2, respectively, while those of the non-BPs-coated sample are 2.6 N and 0.00559 mg/cm^2, respectively. The EDSmapping analysis indicates that an obvious outward diffusion of Cr from the substrate to BPs coated samples occurs after isothermaloxidation. The BPs-coated sample shows the superior adhesion and oxidation resistance compared with non-BPs-coated samples.
