摘要: 扫描微电极法测定金属微区腐蚀电位及电流密度分布是研究金属局部腐蚀的重要手段。本文在评述了目前利用扫描电极测量金属表面电位分布的各种方法基础上,建立了新的实验系统。文中阐述了本方法的电化学理论基础,提出了获得外径低达数微米且具有良好电化学性能的 Ag/igCl参比电极,设计制造了微参比电极在样品表面附近自动扫描的机械装置,研制了具有高输入阻抗,强抗干扰能力的电位分布测定仪器,还介绍了测量电流密度分布等方法。本实验系统具有较高的测量精度,整套装置简易可行,能满足测量实际腐蚀体系的要求。

Abstract：The potential and current density distribution in micro areas on metal surface is significant for studying localized corrosion.A measurement system, the scanning micro-reference electrode techuiques(SRET),is established by the authors and described in this paper.The method of preparing micro- reference electrode,the autodeviee for scanning electrode and the electronic circuit for automatic recording potential distribution are described in detail. Its etectrochemical principle is stated briefly. This apparatus is of higher accuracy with simple and efficient device and meets the requirements of practical experimental systems well.
