Abstract The objective of this work is to analyze the high-cycle fatigue performance of the corroded base material without joints. Constant-amplitude axial tensile fatigue tests were conducted on 55 specimens obtained from the various environments. The infrared thermography was used to track the surface temperature of the specimens. When the corrosion degree is close, the accelerated corrosion test can simulate the atmospheric corrosion to predict the fatigue performance. The mechanism of discreteness of fatigue damage was analyzed from the perspective of energy dissipation. The S-N curves suitable for the Q235 steel in the acid rain corrosion environment are developed.

基于红外热像仪的城市工业大气与实验室模拟腐蚀环境下结构钢高周疲劳性能机理比较

摘要 这项工作的目的是分析无接头腐蚀基材的高周疲劳性能。对从各种环境中获得的 55 个试样进行了等幅轴向拉伸疲劳试验。红外热像仪用于跟踪样品的表面温度。当腐蚀程度接近时，加速腐蚀试验可以模拟大气腐蚀来预测疲劳性能。从能量耗散的角度分析了疲劳损伤离散的机理。开发了适用于Q235钢在酸雨腐蚀环境下的SN曲线。
