摘要/Abstract

摘要： 应用伏安极化法和中性盐雾腐蚀试验研究了张力作用下斜拉桥拉索镀锌钢绞线在5%NaC l溶液中腐蚀行为.腐蚀产物理化性质由XRD、TG-DTA等测试表征.结果表明,镀锌钢绞线的腐蚀电流,即腐蚀速率随试验前施加的张力增加而增大,其产生白锈的盐雾试验周期小于1,经15~22 kN张力作用后的镀锌钢绞线,产生红锈的盐雾试验周期为16,而经0、10 kN张力作用的钢绞线,产生红锈的周期则延长至23,钢绞线腐蚀产物主要是Zn5C l2(OH)8.H2O、Zn4(CO3)(OH)6.H2O和ZnO.

Abstract: Corrosion of steel wire in cables is a major cause of cable-stayed bridge deterioration.The corrosion behavior of galvanized steel wire at different tension is investigated by polarization voltammetry method and neutral salt spray test in 5%NaCl solution.The physical and chemical properties of corrosion products are characterized by XRD and TG-DTA.The result shows that the corrosion current or corrosion rate of galvanized steel wire is larger with increasing the tension,the white rust of galvanized steel wires at different tension appears within one cycle,the red rust appears after 16 cycles at 15~22kN tension,and 23 cycles at 0,10kN tension,and its corrosion products mainly consist of Zn5Cl2(OH)8·H2O、Zn4(CO3)(OH)6·H2O and ZnO.

Key words: cable-stayed bridge, cables, steel wire, corrosion behavior
