Abstract

Monitoring pitting corrosion in real-time and non-destructively is a critical challenge in material science. This study introduces dynamic speckle analysis as an innovative approach to quantitatively track pitting corrosion in metallic structures. Pitting corrosion, a major cause of structural failure due to hole formation, is effectively visualized using this technique. Dynamic speckle patterns, generated by laser light scattering off the corroded surface, reveal both the activity and progression of corrosion. We employ a range of graphical and numerical statistical parameters for detailed analysis. Notable for its low cost, ease of implementation, and quasi-in-situ capabilities, our method offers a significant advancement in the study of corrosion. It holds great promise for broader applications in both natural and industrial settings, presenting a versatile tool for material degradation assessment.
