采用循环伏 安法评价了防锈油的防锈性能 ,比传统测试方法简单、快速 ,为克服该方法存在的电位区间、扫描次数不易确定因素 ,提出了扩展循环伏 安法 ,并用此方法对防锈油的性能进行了评价 ,测试结果同湿热试验结果相一致。这表明扩展循环伏 安法完全适用于评价防锈油的性能 ,较循环伏 安法更为方便、可靠 The cyclic voltammetry method was used to evaluate the antirust properties of anti-rust oil. Compared with the traditional method, the anti-rust property of antirust oil is simple and fast. To overcome the potential interval and the number of scanning times, the extended cyclic voltammetry The performance of anti-rust oil was evaluated, the test results are consistent with the results of wet heat test. This shows that the extended cyclic voltammetry method is fully suitable for evaluating the performance of anti-rust oil, more convenient and reliable than the cyclic voltammetry
