| 英文摘要 | Different levels of tensile stress were applied to H62 brass during immersion experiments conducted in 3.5 wt% NaCl solution. The stress-corrosion environmental synergy mechanism was systematically investigated through electrochemical characterization, SEM observations, and COMSOL-based multiphysics field coupling modeling. Significant regulatory effects of stress levels on corrosion mechanisms were demonstrated. Specifically, elastic-range stress was found to induce protective oxide film formation through electrochemical passivation processes, resulting in corrosion rate reduction. Conversely, intensified mechanical-electrochemical synergy under high stress conditions was identified as the primary acceleration mechanism for localized corrosion. Critical thresholds were quantitatively determined, with microcrack initiation observed at 75 % of the yield strength (6ys) and irreversible failure triggered by plastic deformation at 110 % 6ys. Based on these findings, a stress control threshold of below 50 % 6ys is recommended for brass components in simulated marine environments to ensure corrosion protection effectiveness. This theoretical framework establishes fundamental criteria for stress design limitations, corrosion prevention strategies, and structural integrity monitoring in marine engineering applications. |
