采用热分解法在钛基体上制备了不同Sn元素配比的Ru-Sn-Ti氧化物涂层;探究了温度对钛电极涂层电化学性能的影响。通过扫描电镜、X射线衍射、阳极极化曲线,研究了该氧化物涂层电极的物理性能和电化学性能。结果表明:由热分解法制得的三元涂层在375℃、Sn占质量比为4%的条件下,涂层表面组织均匀细密,裂纹宽度小,晶粒尺寸细化程度最好,电化学性能最优。 The Ru-Sn-Ti oxide coatings with different Sn ratios were prepared by thermal decomposition method on titanium substrate. The effect of temperature on the electrochemical performance of titanium electrode coatings was also investigated. The physical and electrochemical properties of the oxide coated electrode were investigated by scanning electron microscopy, X-ray diffraction and anodic polarization curves. The results show that the ternary coating prepared by thermal decomposition has a uniform microstructure, small crack width and fine grain size under the condition of 375 ℃ and 4% Sn. Optimal performance.
