摘要/Abstract

利用交流阻抗谱和极化曲线研究比较了四组不同晶粒尺寸的螺纹钢在模拟海水液(3.5% NaCl)中短期电化学腐蚀行为; 利用硼酸缓冲液中钝化膜的Mott-Schottky 理论比较了各试样在不同阳极极化电位下的钝化膜的优劣性. 结果表明, 在14 d 的模拟海水短期浸泡期间, 细晶粒螺纹钢在后期表现出较大阻抗值和较小的自腐蚀电流密度, 耐蚀性能优于粗晶粒试样. 在硼酸缓冲液中形成的钝化膜表现出典型的n 型半导体性能, 公共钝化区间为-0.15～0.8 V. 在选取的-0.1, 0.2, 0.5 V 三个不同极化电位下, 细晶粒螺纹钢在硼酸缓冲液中的钝化膜稳定性、耐蚀性弱于粗晶粒螺纹钢. 在0.5 V 的外加电压下试样钝化膜的内层膜消失, 钝化膜的施主浓度最低, 膜最为致密、稳定.

The effect of grain size on the electrochemistry behavior of rebars in 3.5% NaCl solution were investigated using electrochemical impedance spectroscopy (EIS) and polarization curves. The Mott-Schottky curves at different potentials were employed to compared the passive film formed on the rebars with different grain size. The results showed that fine-grained rebars had larger impedance value and less corrosion current density than coarse-grained rebars after immersed 14 d, and the corrosion resistance of fine-grained rebar was better. The passive film formed in borate buffer solution behaviored like a classical n-type semiconductor, and the passive ranges of the rebars were all between -0.15 and 0.8 V. The stability and corrosion resistance of the passive film formed on fine-grained rebars were worse than those of coarse-grained rebars at the potential of -0.1, 0.2 and 0.5 V. The subcoat of the film vanished at the potential of 0.5 V. The donor densities was minimum, and the film was most compact and stable.

Key words: corrosion resisting, grain size, rebar, Mott-Schottky
