The use of electron microscopy techniques have various applications in the corrosion research. Scanning electron microscopy (SEM) and the chemical analysis of the corrosion products are commonly found in the corrosion related literature. Also, microstructural characterizations based
on transmission electron microscopy (TEM) and electron diffraction patterns are widely used. More recent microscopy technicwes such as the atomic force microscopy (AFM) have also been used for corrosion research. One of the main advantages of this technique is that allows to
perform microscopy observations in situ during corrosion experiments. In this work some application of these techniques to the study of microbiologically induced corrosion (MIC) of stainless steel in natural seawater are presented.
