摘要
利用电化学方法研究了 3号碳钢在两种特制导电水泥中的腐蚀电流 Icorr和极化电阻 Rp 随时间的变化关系 ,求出了 3号碳钢在两种导电水泥中的年腐蚀速度 ,并确定了其在两种导电水泥中的耐腐蚀等级。实验表明 ,3号碳钢在导电水泥 A中的腐蚀速度小于 0 .0 3 m m/ a,符合防雷接地技术的要求 ,从而依此确定导电水泥
DENG Zhao-yang, PENG Zhong-dong, SONG Hai et al(31) The changing relationship of corrosion current Icorr and polarization resistance Rp of A3 steel in two kinds of special conduction cements with time has been studied by electrochemical means. The grades of A3 steel in two conduction cements were determined. It was shown that the corrosion rate of A3 steel in conductive cement A, <0.03 mm/a, is in accord with the technolgical requirements of thunderproof and ground connection.
