可追溯到20世纪60年代初的文献表明，在实验室条件下，交流电流会导致阴极保护钢的腐蚀。然而，直到最近，很少有证据表明，阴极保护结构的交流腐蚀可能是实际问题。在安大略，在过去的六年里，作者已经调查了几个腐蚀异常发生在管道暴露于感应交流干扰。本文讨论了一些这样的情况下，交流腐蚀被怀疑的测试程序用于识别交流腐蚀进行了讨论，因为是一些方法，以尽量减少交流腐蚀的风险。
Literature dating back to the early 1960’s has shown that AC current can cause corrosion of cathodically protected steel under laboratory conditions. Until recently however, there has been little evidence to suggest that AC corrosion of cathodically protected structures may be of practical concern. In Ontario over the past six years, the authors have investigated several corrosion anomalies occurring on pipelines exposed to induced AC interference. This paper discusses a number of such cases where AC corrosion was suspected The test procedures used to identify AC corrosion are discussed, as are some of the methods for minimizing the risk of AC corrosion.
