To begin with, SEM (scanning electron microscopy) is an essential electron microscopy technique for the analysis of the aspect of a material. Indeed, the studied material is scanned by a fine beam of electrons without destroying it, allowing to obtain qualitative images of the surface.
Thanks to the SEM, it is possible to study healthy and polluted surfaces, with and without defects, fracture faces, corrosion areas for a detailed analysis of materials and surfaces.
The examination of the aspect of a material by SEM, allows, first of all, to check and to adapt your manufacturing processes. Indeed, the SEM, by the quality of the image obtained at the end of the analysis, makes it possible to examine in detail the surface of the material.
In addition, electron microscopy also allows you to adapt the implementation of surface treatment or cleaning processes.
