摘要
在沈阳土壤腐蚀试验中心站 ,用便携式土壤腐蚀测试仪及土壤环境因素测试仪现场原位测试了土壤的电导、氧化还原电位、地温等土壤理化性质 ,以及碳钢的腐蚀速率变化情况 .试验结果表明 ,土壤的电导受地温的影响显著 ,土壤中微生物腐蚀随着地温升高而显著增强 .在春夏季节交替时 (3月～ 7月 )碳钢的腐蚀速率最大 ,而在冬季(12月～ 3月 )碳钢的腐蚀速率最低 .原位测试结果与失重值对比表明 。
In situ measurement of corrosion rate of mild steel and soil factors has been carried out in Shenyang soil site.It showed that soil conductivity and soil salt content ,corrosion rate of mild steel increased with the raising of soil temperature.At the time of alternate spring and summer (from April to July),on account of underground temperature and soil conductance rising acutely,corrosion rate of mild steel was the highest.The error of copper between the in-situ corrosion and soil natural corrosion was not high,and the error reduced gradually with the extension of the test period.Therefore,the instrument of soil corrosion can measure quickly the corrosion rate of mild steel in-situ.
