摘　　要：扫描Kelvin探针力显微镜(SKPFM)是在原子力显微镜(AFM)的基础上应用扫描Kelvin探针(SKP)技术开发的检测表征手段,它能够在获取材料表面纳米级分辨率形貌的同时,原位得到样品表面高分辨率的接触电势差分布图,为揭示腐蚀反应机理提供了崭新的思路,近年来发展迅速。本文介绍了SKPFM两种工作模式的基本原理,总结了SKPFM在应用中的问题,并讨论了SKPFM和传统扫描Kelvin探针技术(SKP)的优缺点,重点综述了SKPFM在腐蚀科学研究中的应用,最后展望了SKPFM的发展方向与应用前景。Scanning Kelvin probe force microscopy(SPFKM)is a material measuring and characterizing technique which applies scanning Kelvin probe on the basis of atomic force microscopy(AFM)and has been gaining momentum in recent years.It involves simultaneously the nanometer-level topography measurement and the in-situ high-resolution volta potential mapping,thereby providing a novel insight in investigating the mechanisms of materials’corrosion behaviours.The present paper sketches out the principles with respect to the two working modes of SKPFM,summarizes the unresolved issues that have emerged in SPFKM’s application,and also renders a comparative discussion between SKPFM and the traditional SKP technique.The review offers an elaborate delineation about the application of SKPFM in corrosion science,and ends with a rough description of the opportunities and challenges.
