Abstract The corrosion and microstructure behavior features, such as steel strand corrosion and corrosive wear of the as-prepared composite coatings and substrates were investigated. It is found that the experimental pitting depth followed a normal distribution and both the location and scale parameters increased with the corrosion degree. The fatigue test results indicated that corrosion could cause a significant decrease in the fatigue life of corroded steel wires. The substrate exhibited corrosion-accelerating wear, while the coatings exhibited wear accelerating corrosion. A method based on 3D measurements and AFGROW software was proposed to predict the remaining fatigue life of corroded steel wires. The predicted fatigue lives agreed well with the test results.

桥梁用钢绞线的腐蚀与显微组织行为

摘要 研究了制备的复合涂层和基体的腐蚀和微观结构行为特征，如钢绞线腐蚀和腐蚀磨损。发现实验点蚀深度服从正态分布，位置和尺度参数都随着腐蚀程度的增加而增加。疲劳试验结果表明，腐蚀会导致腐蚀钢丝的疲劳寿命显着降低。基体表现出加速腐蚀磨损，而涂层表现出加速腐蚀磨损。提出了一种基于3D测量和AFGROW软件的方法来预测腐蚀钢丝的剩余疲劳寿命。预测的疲劳寿命与测试结果非常吻合。
