Fractal dimension is a versatile method to study and evaluate corrosion from the point of view metallic conditions, namely: surface roughness, electrochemical measurements microscopy images. Aluminum corrodes at different rates, under pH electrolytes with or without presence chloride ions. In this work, roughness for aluminum electrolytes: acid, chlorides, neutral basic solutions, were obtained. It was measured obtained using optic techniques. The results Electrochemical Impedance Spectroscopy (EIS) Noise Measurements (ENM), Digital Holographic Microscopy (DHM), Scanning Electron Microscope (SEM) micrographs their respective Dimension analysis obtained.. For experimental techniques fractal presented, reflecting condition as function solution.
