| 英文摘要 | The corrosion mechanism of steel wire for bridge cables (Q235) under coupled Cl--stress effects is systematically investigated. A synergistic interaction between Cl- and tensile stress has been demonstrated through integrated experimental characterization and computational simulations to accelerate material failure by enhancing corrosion product transformation. Under low Cl-/stress levels, corrosion kinetic is relatively sluggish; however, stress concentration at defects becomes increasingly pronounced as loading parameters increase. Microcracks facilitate Cl- penetration to crack tips, thereby enhancing anodic dissolution and promoting localized corrosion. Tensile stress intensifies corrosion-mechanical coupling by increasing dissolution current density and shifting electrode potential, resulting in greater acceleration of corrosion than the influence of Cl- alone. A developed computational model demonstrates time-dependent evolution of stress-corrosion interactions. Statistical analysis indicates that stress shows a dominant influence (standardized coefficient 1.32), while Cl- contributes most significantly to corrosion initiation (contribution >35 %). Critical threshold levels are identified at Cl- >= 5.0 wt% and stress >= 50 %sigma(ys). Effective corrosion control is achieved primarily through stress reduction and Cl- management (core strategy), supplemented by maintenance for time-effect mitigation (17 % contribution). The maximum prevention efficiency is realized when high-risk parameter combinations are avoided during the implementation of the control strategy. |
