| 摘 要： | 利用动电位极化和表面形貌观察技术，结合电容-电位曲线测量和Mott-Schottky分析，探讨了糖苷化合物对钢筋在含3.5%NaCl的Ca(OH)2饱和溶液中的缓蚀行为和表面钝化膜性能的影响。结果表明，糖苷阻锈剂的加入可有效减缓钢筋的腐蚀，促进钢筋表面的钝化，提高钢筋耐Cl-侵蚀能力；阻锈剂虽未改变钢筋表面钝化膜的半导体性能，但钝化膜内载流子密度却显著下降；钝化膜致密性分析表明，随糖苷浓度增大，钢筋表面钝化膜稳定性和致密性逐渐增强，耐蚀性提高。 |
| 关 键 词： | 糖苷阻锈剂 钢筋 钝化膜 |

| Abstract: | The effect of PG (pentaerythritol glycoside) on the performance of the passive film on steel rebar in Ca(OH)2 saturated solution containing 3.5%NaCl, which was designed to simulate solutions in concrete pores, was investigated by mean of polarization curve measurement, Mott-Schottky analysis technique and surface analysis. The results showed that the PG could enhance the stability of the adsorption film formed on the metal surface. The curves of |
