“…In addition, differences in the surface state, including topography, properties and composition, have significant influence on the fretting corrosion mechanism of the alloy tubes. For example, many hardening technologies, such as coating and microplastic deformation treatments, have been applied to improve the surface mechanical properties and microstructure of 690 alloy tubes and thereby enhance their fretting corrosion resistance (Yin et al , 2022; Kang et al , 2023). Furthermore, the surface oxidation conditions affect the wear and corrosion resistance of the material.…”

Purpose The purpose of this paper is to study the effect of surface salt spray duration on the fretting wear and electrochemical corrosion behaviors of Inconel 690 alloy. Design/methodology/approach A high-temperature steam generator was applied to salt spray test samples, a fretting wear rig was used to realize the damage behavior tests, an electrochemical workstation was applied to analysis the changes of each sample’s corrosion dynamic response before and after fretting wear. Findings The thickness of the oxide film that formed on sample surface was increased with the salt spray duration, and somewhat it could act as lubrication during the fretting wear process; however, the corrosive chloride would accelerate the fretting mechanical damage behavior. Originality/value In a salt steam spray condition, the fretting tribo-corrosion behaviors of Inconel 690 alloy surface was studied.
