| सारांश: | Title screen This study investigates the influence of carbon steel surface topography on the corrosion inhibition efficiency of hybrid nanostructured inhibitors based on zinc oxide nanoparticles (nZnO), both individually and in combination with thiourea or pectin. Surface roughness was systematically varied using abrasive treatments with grit sizes ranging from 140/125 to 7/5 µm, and its correlation with corrosion behavior was evaluated through weight loss measurements, potentiometry, and optical microscopy in aggressive acidic and saline environments. The results demonstrate that surface roughness significantly affects both the corrosion rate and the protective mechanism of the inhibitors. Smooth surfaces (28/20 and 7/5 µm) favored the formation of uniform barrier layers by nZnO, leading to predominant anodic inhibition. In contrast, the ZnO/pectin hybrid system exhibited superior performance on rougher surfaces, attributed to enhanced polymer adsorption and mechanical interlocking within micro-irregularities. The ZnO/thiourea combination showed a mixed inhibition mechanism with synergistic effects most pronounced at intermediate roughness levels. The findings highlight the critical role of tailoring inhibitor composition to specific surface topographies to optimize corrosion protection in practical applications Текстовый файл AM_Agreement |
