State-of-the-Art on Fatigue Properties of Corroded Steel Members Subjected to Marine Atmosphere
Fatigue failure is one of the main causes of metal structure damage,and if corrosion is considered,the problem becomes more complex.Domestic and foreign scholars have conducted systematic and comprehensive research on the fatigue properties of corroded steel components.The paper critically reviewed and analyzed the state-of-the-art on fatigue properties of corroded steel elements subjected to marine atmosphere in terms of electrochemical corrosion process,corrosion characterization,fatigue properties of corroded steel components.It was found that the electrochemical process of steel corrosion,the general laws of fatigue properties of corroded steels,the characterization of corroded steel surfaces based on a single index have been clearly understood.However,the accurate evaluation of the evolution of fatigue properties of corroded steel structures still faces significant challenges.It is suggested to further identify the spatiotemporal distribution and random models of morphological characteristics of corroded steels,the similarity of steel corrosion mechanisms between natural and artificial environmental conditions,the random evolution mechanism of fatigue properties of corroded steel structures in marine atmospheric environment,as well as the control and improvement of the fatigue properties of corroded steel structures.
