磁场对X60钢材料在长沙地区土壤中腐蚀行为的影响
Effect of Magnetic Field on Corrosion of X60 Pipeline Steel in Soil of Changsha Area
摘 要
采用失重法，电化学方法，腐蚀形貌分析等研究了磁场对X60管线钢在长沙磁浮快线与西气东输管道潜湘支线交叉点处土壤中的腐蚀行为影响规律。结果表明：磁场的存在加速了X60钢在长沙土壤中的腐蚀；埋设相同时间，试样在无磁场条件下的腐蚀失重最小，在强磁场条件下的腐蚀最严重，其埋设28 d的腐蚀速率达到0.068 mm/a。

Abstract
The effects of magnetic field on the corrosion behavior of X60 pipeline steel in the soil at the intersection of Changsha maglev express line and West-East gas pipeline Qianxiang branch were studied by weight loss method, electrochemical method and corrosion morphology analysis. The results show that the presence of magnetic field accelerated the corrosion of X60 steel in Changsha soil. When the samples were buried for the same time, the corrosion weight loss under the condition without magnetic field was the smallest, and the corrosion weight loss under the condition with strong magnetic field was the most serious. Under strong magnetic field conditions, the corrosion rate of the samples embedded for 28 d reached 0.068 mm/a.
