摘　　要：建立了实验室模拟海洋环境腐蚀试验装置,可以模拟浪花飞溅区、海水潮差区、海水全浸区等多种海洋腐蚀环境。研制了一种可用于浪花飞溅腐蚀监检测的电化学传感器,利用该传感器测试了模拟腐蚀试验架浪花飞溅部位的电化学噪声特征,分析比较了不同部位噪声电阻R_n值,表明涂覆清漆的部位耐蚀性能优于裸露部位。An analog device of the marine environment corrosion in laboratory conditions was established. This device can simulate a variety of marine corrosion environments, such as wave splash zone, tidal zone and sea water immersion zone, etc. A new type of electrochemical sensor for the waves splash zone corrosion was developed. Electrochemical noise characteristics of simulated corrosion test rack in different parts of the surface were obtained by using this sensor and noise resistance Rn of different parts were compared and analyzed. The results showed that the anticorrosion performance of part B was better than part A.
