【摘要】 采用丝束电极，对涂油金属的电化学不均匀性进行了研究。结果表明，丝束电极表面电化学状态是均匀的，涂油金属的腐蚀电位及油膜电阻的分布是不均匀的；油溶性缓蚀剂的加入，可以使涂油金属的腐蚀电位正移，可以减少或消除油膜低阻区。更多还原

【Abstract】 The electrochemical inhomogeneity on oil painted metal was studied by wire beam electrode. Results showed that the electrochemical state on the surface of wire beam electrode was homogeneous, while the distributions of corrosion potential and DC resistance of oil film were inhomogeneous on oil painted metal, The corrosion potential on substrate would shift to positive direction, low DC resistance area could be decreased and eliminated by adding oil soluble inhibitors.更多还原
