Abstract

See full text

The present invention refers to a procedure which includes the following objectives:

    a) To determine the morphology of the micro and nanocavities produced by chemical and/or microbiological corrosion in metallic materials, in the space of three dimensions as well as the effective advance of corrosion, the true length of corrosion cavities and their associated parameters: corrosion vectors, corrosion intensity and determination of the cavities diameter/true length of corrosion ratio, applying scanning electron microscopy (MEB) techniques, and analytic, gravimetric and volumetric formulations;b) To quantitatively determine the rate of chemical and/or microbiological corrosion in metallic materials, through their volumetric and gravimetric properties; andc) To obtain a graphic interface to access the numeric information and the micrographs in a simple and friendly manner.
