Corrosion phenomena are usually difficult to recognize without a deep knowledge of the electrochemical properties of materials, this creates difficulties in the analysis of corrosion in practice, control measures are developed through image processin

X-ray computed tomography is a technique that provides a high level of detail in three-dimensional (3D) inspections of composite materials, but the acquisition of phase contrast together with absorption contrast in traditional tomography makes it dif
