摘要
采用缩比模型理论建立船舶外加电流阴极保护系统,研究船体表面电位分布的影响因素之间关系。结果表明,单区阴极保护系统辅助阳极位置决定船体表面电位曲线的形状,参比电极影响曲线电位值的大小;增加阳极数量能够优化电位分布,降低曲线电位的波动。试验证明,基于缩比模型理论的船舶表面电位测量方法是一种方便、有效的测量手段,为进一步优化外加电流阴极保护系统提供新的研究途径。
A physical scale modeling technique has been used to study the influecing factors which determine the distribution of shipbull surface potentials for impressed current cathodic protection（ICCP）. Results from a singlezone system showed that the shape of potential profile was determined by anode location and its level by the setting of reference electrode. The potential was optimized by increasing the number of anode. It is proved that the use of physical scale model provides a practical and flexible tool for the collection of data suitable for the further development of design criteria for ship ICCP.
