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