摘要
研究了钢芯铝绞线用钢的局部腐蚀。结果表明：该钢中添加稀土元素改善了其耐蚀性能。点蚀敏感性明显降低，点蚀电位提高５０～７０ｍＶ；坑孔扩展速率明显下降，在宏观阴极极化－６００ｍＶ的条件下，耐蚀率提高５０％～１５０％。
Local corrosion of the steel for aluminium cable steel reinforced is investigated The results show that the corrosion resistance of steel is obviously improved by adding rare earth The pitting corrosive sensitivity of steel is significantly decreased,the pitting corrosive potential is increased with 50～70mV and the anti corrosion rate is improved with 50%～150% under the conditions of macro cathode polarization-600mV
