| Abstract | 利用动电位极化曲线、电化学阻抗谱图（EIS）和Mott-Schottky分析等电化学测试手段．探讨了Fe—10Cr纳米涂层在0.05mol／L H2SO4＋0.5mol／LNaCl溶液中的腐蚀行为．研究表明，与铸态合金相比，溅射纳米涂层表面钝化膜的化学稳定性和再钝化性能明显提高；二者的钝化膜均具有p型半导体结构特征．但溅射纳米涂层表面钝化膜的载流子密度和平带电位都比较低，导致钝化膜中金属离子的传输速度较低，纳米橡层表面钝化膜的化学稳定性增强。 |
| Other Abstract | The corrosion behavior of Fe - 10Cr sputtering coating with nanoscale grain size was investigated in 0.05 mol/L H2SO4 ＋0.5 mol/L NaCl aqueous solution using polarization curves, EIS and Mott -Schottky analysis. The results indicated that the chemical stability and repassive ability of passive film formed on Fe - 10Cr nc coating was apparently improved. The passive films on both Fe - 10Cr nc coating and cast alloy have p - type semiconducting behavior. The lower acceptor density and flat - band potential of the passive film in comparison with Fe - 10Cr cast alloy lead to the high chemical stability and repassive ability for the passive film on the sputtering coating. |
