摘要
介绍了原子力显微镜(AFM)的工作原理、操作模式以及在微生物腐蚀研究中的应用,包括原位观察细菌和微生物膜形貌、测量力-距离曲线研究微生物在材料表面的粘附力、测量材料表面电位的不同得知生物膜厚度和腐蚀程度.同时还介绍了电化学原子力显微镜的应用.
Recently, atomic force microscope （AFM） has been applied in microscopical characterization of material surface. The principle, operating mode and application of atomic force microscopy （AFM） in microbiologically influenced corrosion （MIC） are introduced in this paper. The topography of bacteria and biofilms may be observed in situ. Adhesion force may be studied by measuring the force versus distance curve. Thickness of biofilms and degree of corrosion may be revealed by surface potential. Some application is discussed in corrosion field of EC - AFM.
