电镀锌生产线导电辊腐蚀失效原因与机理

An Investigation to Corrosion Failure of Conductor Rolls in Electrogalovanizing Line

摘要: 在实验室模拟生产现场工况条件,通过浸泡实验和电化学方法等,研究了铜和304不锈钢的腐蚀行为;分析了介质条件(温度、Fe³⁺及Cl^-浓度)的影响;特别考虑了间断性的阴极状态对材料腐蚀的作用。提出了生产线上导电辊产生腐蚀失效的原因和机理。

Abstract: The corrosion behavior of Cu and SS304 has been studied by means of the immersing test and the electrochemistry method under the conditions simulating industrial site.The influences of medium condition,particularly periodic cathodic state on material corrosion have been investigated.The reason and mechanism of corrosion failure of the conductor rolls have been proposed.
