For coatings that serve as protective barriers for steel structures, their adhesion strength is a core indicator determining protective efficiency and service life. This paper reviews the research progress on the bonding performance of organic protective coatings for steel structures, analyzes the factors influencing the evolution of bonding performance and their respective mechanisms, summarizes the testing methods for coating bonding performance, and elaborates on the construction and application of interface cohesive models. The analysis shows that the variation mechanisms induced by single factors have currently been revealed, and the existing interface constitutive models focus on the interface damage and fracture behavior under the action of force fields.In the future, it is necessary to further study the coupled action mechanisms and influence patterns of multiple factors, and to construct an interface behavior prediction model that considers the coupling of multiple factors (environmental conditions, fire high temperatures, and stress), so as to provide references for the design, damage detection, and performance repair of protective coatings for steel structures.
