为防止由于舰船表面电位分布不均匀而造成舰船腐蚀,采用缩比模型理论建立舰船外加电流阴极保护系统,研究船体表面电位分布影响因素之间关系.结果表明,单区域外加电流阴极保护系统的辅助阳极和参比电极位置改变将影响船体电位的分布.辅助阳极位置影响船体保护电位曲线的形状,而参比电极位置决定各曲线保护电位值的大小.外加电流阴极保护系统中增加阳极的数量和布置均匀时,可优化船体保护电位分布,且曲线波动小.试验证明,基于缩比模型理论的舰船保护电位测量方法是一种方便、有效的测量手段,可为进一步优化外加电流阴极保护系统提供新的研究途径.
In order to prevent the corrosion of warships caused by the non-uniform potential distribution on the surface of ships, a negative current protection system of warship applied current was established by using the shrinkage model theory to study the relationship between the influencing factors of potential distribution on the hull surface.The results showed that the single-area applied current cathodic protection The position of auxiliary anode and reference electrode will affect the distribution of hull potential.The position of auxiliary anode affects the shape of hull protection potential curve and the position of reference electrode determines the value of each curve protection potential.Adding current cathodic protection system adds anode The distribution of protection potential of hull can be optimized and the curve fluctuates little.The experiments show that the measurement method of ship protection potential based on the shrinkage model theory is a convenient and effective measure to further optimize the applied current Cathodic protection systems provide new avenues of research.
