摘要/Abstract

摘要： 使用接触角测量和电化学技术研究了三相线界面区(TPB)宽度在分散液膜下金属腐蚀过程中的作用.研究发现,阴极极限电流和腐蚀电流密度随TPB宽度增加而线性增大,表明TPB宽度对气/液/固多相体系腐蚀过程具有重要影响.因此,可根据TPB宽度评价分散液膜厚度对大气腐蚀速率之影响.

关键词: 气/液/固三相线界面区, TPB宽度, 液膜厚度, 接触角, 大气腐蚀

Abstract: The roles of TPB(Three-Phase Boundary) width in the corrosion processes of metals under dispersed water films were investigated by electrochemical techniques combined with contact angle measurement.It is found that both cathodic limiting current density and corrosion current density linearly increases with increasing the TPB width,confirming the important role of TPB width in gas/liquid/solid multiphase corrosion systems.Based on above results,the effect of water film thickness on atmospheric corrosion rate was quantitatively evaluated by the TPB width.

Key words: gas/liquid/solid three-phase boundary zone, TPB width, water film thickness, contact angle, atmospheric corrosion
