纯铜的土壤腐蚀原位测试

In-situ measurement of soil corrosion of copper

在沈阳土壤腐蚀试验中心站现场原位测试了土壤的理化性质和纯铜的腐蚀速率变化情况。土壤理化性质测试结果表明 ,土壤的电导及含盐量随地温的升高而增大 ,土壤中微生物腐蚀随着地温升高而显著增强 ,原位测试结果显示纯铜的腐蚀速率随着地温的升高而增大 ,与实测质量损失值对比 ,两者误差较小 ,因此纯铜可作为一种原位测试土壤腐蚀性的标准电极材料。

In situ measurement of corrosion rate of copper and soil physico chemical factors was carried out in Shenyang soil site. The results show that soil conductivity, salt content and bacterial corrosion of soil increase with raising soil temperature, and the corrosion rate of Cu also increase with the soil temperature. The comparison of in situ mass loss with actual measured value shows that the error between them is very little. Therefore, copper may become a standard measuring electrode for soil corrosion.
