APPLICATION OF ATOMIC FORCE MICROSCOPE IN STUDY OF MICROBIOLOGICALLY INFLUENCED CORROSION
AFM技术在微生物腐蚀研究中的应用

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.
