碳钢在NaHCO3溶液中的阳极极化行为
Anodic Polarization Behaviors of Carbon Steel in Bicarbonate Solution
摘要
Abstract
The anodic polarization curves of mild steel were measured in sodium bicarbonate solution of various concentrations, and the surface products were analyzed by XPS. Two anodic current peaks and two passive zones are observed in all the curves. When HCO3- ions concentration is below 0.1mol/L, the two peaks are so close that the first passive zone is difficult to be observed. When HCO3- ions concentration is above 0.1 mol/L, the first peak appears clear, while the second becomes smaller. The XPS results indicate that the out layer of film formed at a higher potential is mainly composed of Fe2O3, and the inner film is a mixture of ferrous and ferric oxide.关键词
