中文摘要：

电气化学的阻抗光谱学，周期的 potentiodynamic 极化大小，并且与精力散的X光检查光谱学一起扫描电子显微镜学被用来在钝化能力和导致氯化物的腐蚀行为上调查工厂规模和锈层的影响常规低碳( LC )钢并且低合金( LA )在模仿的水泥的钢毛孔答案。结果证明那工厂规模在各种各样的电气化学的阶段对两钢的腐蚀电阻施加不同影响。我们建议 LA 钢的高长期的腐蚀抵抗主要通过一个逐渐地形成的协议，支持者和散布得好的充实 Cr 的内部锈层的 synergistic 效果和工厂规模的物理障碍保护效果被完成。

英文摘要：

Electrochemical impedance spectroscopy, cyclic potentiodynamic polarization measurements, and scanning electron microscopy in conjunction with energy-dispersive X-ray spectroscopy were used to investigate the influence of mill scale and rust layer on the passivation capability and chloride-induced corrosion behaviors of conventional low-carbon（LC） steel and low-alloy（LA） steel in simulated concrete pore solution. The results show that mill scale exerts different influences on the corrosion resistance of both steels at various electrochemical stages. We propose that the high long-term corrosion resistance of LA steel is mainly achieved through the synergistic effect of a gradually formed compact, adherent and well-distributed Cr-enriched inner rust layer and the physical barrier protection effect of mill scale.
