| 目的 弄清金属材料在天然河水中的腐蚀电位变化规律，获得它们的腐蚀电位序。方法 利用自行研制的多通道电位自动采集装置，测试金属材料在武汉长江水中的腐蚀电位。结果 获得了24种金属材料在天然河水中的腐蚀电位-时间曲线及腐蚀电位序图谱。 结论 金属材料在天然河水中初期腐蚀电位变化较快，同种类金属腐蚀电位变化规律基本相同，不同种类的金属材料腐蚀电位变化规律不同；金属材料在天然河水中的稳定腐蚀电位从低到高大致为镁阳极、纯锌、铝合金、铸铁、碳钢、低合金钢、铜合金和不锈钢。 |

| Objective To analyze change rules of corrosion potential in natural water and obtain their galvanic series. Methods The corrosion potential of metals in the Yangtze River of Wuhan section was measured by multi-channel potential data acquisition device which was developed by ourselves. Results The potential-time curves and galvanic series graph for corrosion of 24 metals in natural river water were obtained. Conclusion The corrosion potential of metals in natural water changes quickly in the preliminary stage. The corrosion potential change rules of the same kind of metals are basically the same. The corrosion potential change rules of different kind of metals are different. The stable corrosion potential series of metals in natural river water (from bottom to top) is magnesium anode, pure zinc, aluminium alloy, iron casting, carbon and low alloy steel, copper alloy, stainless steel. |
