Research Progress on Corrosion Behavior of Materials under Wet-dry Cyclic Conditions
With the development and utilization of marine resources,the corrosion and protection of materials under wet-dry cyclic conditions received increasing attention.In environments such as spray splash zone,tidal zone,atmospheric environments containing corrosive media,facilities and buildings using deicing salt,reinforced concrete structures under wet-dry cyclic conditions,and wet-dry alternating sandy soil environment,materials were subjected to alternating dry and wet cycles caused by the change of temperature and humidity of water-containing corrosive media for a long time.Their corrosion behavior was different from that in dry and fully immersed environments.Therefore,the research status and progress in China and abroad under wet-dry cyclic conditions were reviewed in this paper.The corrosion behavior,corrosion influencing factors,and corrosion experimental methods of various materials in different dry and wet alternating environments were introduced,so as to provide some theoretical experience for the study and application of materials.
