【摘要】 应用阵列电极测量不同阴离子介质中有机涂层／铁电极界面电位分布图，研究腐蚀发生、发展过程．实验结果表明：腐蚀优先发生在有机涂层／铁电极界面边缘．涂层一旦破裂，在Ｃｌ－介质中腐蚀很快发生并不断发展，在ＮＯ－３介质中腐蚀也很快发生，一段时间后就逐渐受抑制，而在ＣＯ２－３介质中腐蚀不发生．与常规电极相比，阵列电极能给出更详细的腐蚀界面的电化学参数．更多还原

【Abstract】 The array electrode as a new electrochemical technique is applied to map the corrosion potential imaging and to sutdy the corrosion process at the interface of organic coating/iron after being immmersed in solutions containing different kinds of anion. The experiment results indicated that the corrosion preferentially occured on the edge of the surface of organic coating/iron and ,when the coating was broken down ,the crrosion occured and developeed in Cl - solution, however corrosion occured first and then was suppressed in NO - 3 solution and the corrosion was prevented in CO 2- 3 solution. In comparison with the traditional methodpolarization curve, more detailed crrosion information of coating/iron interface can be obtained from the array electrode technique.更多还原
