用一种新的化学溶液沉积方法在双轴织构NiW(200)合金基底上制备了涂层导体用稀土氧化物RE203(RE=Y,Sm,Eu,Dy,Yb)缓冲层。分别利用X射线衍射,扫描电子显微镜,原子力显微镜对制得的RE2O3缓冲层的相结构、织构、表面形貌和平整度进行了检测。结果表明,RE2O3缓冲层具有较好的双轴织构,表面平整无裂纹。
A novel chemical solution deposition approach was employed for the preparation of coated-conductor-used RE203 (RE=Y, Sm, Eu, Dy, Yb) buffer layers on the biaxial NiW(200) alloy substrate. X-ray diffraction (XRD), scanning electron microscope (SEM), and atomic force microscope (AFM) were used to characterize the phase structure, texture, surface morphology and roughness of the as-received RE2O3 buffer layers. Results show that the obtained RE2O3 buffer layers have well biaxial texture and their surface is smooth and crack free.
