Current Density and Corrosion Morghology of Steel Bar Corrosion in Reinforced Concrete
摘 要
研究了辅助电极布置位置对钢筋锈蚀外形的影响，定量分析了4种辅助电极布置情况下的钢筋锈蚀分布。结果表明：合理布置辅助电极可产生与自然状态下相似的钢筋锈蚀外形。通电锈蚀试验证明了该仿真模型的可靠性。

Abstract
The influence of the location of auxiliary electrode on the corrosion morghology of steel bar was studied, and the distribution of steel bar corrosion under four auxiliary electrode arrangements was quantitatively analyzed. The results show that a reasonable arrangement of the auxiliary electrode could produced the corrosion morghology of the steel bar similar to the natural state; power-on corrosion test proved the reliability of the simulation model.
