| Abstract | This study investigates the surface degradation of phenolic-based brake friction composites under corrosive NaCl environments, emphasizing morphological analysis through digital image processing. The specimens were subjected to both vapor-phase and immersion conditions to simulate real-world corrosion scenarios. Surface changes were characterized via optical microscopy, Otsu-based grayscale binarization, and roughness profiling. The results indicated that vapor-phase exposure caused more uniform corrosion, but with smoother surfaces, while immersion led to localized and irregular damage. Post-corrosion dry friction tests showed a marked reduction in the coefficient of friction, attributed to surface smoothing and lubricious corrosion product formation |
