Corrosion Behavior of Weathering Test Steel for Bridge under the Neutral Wet/Dry Alternate Condition

摘要：

The corrosion behaviors of the high-performance weathering test steel for bridge and the reference (09CuPCrNi-A) were symmetrically studied under 3.5％ NaCl neutral wet/dry alternate condition, revealing their dynamics line tendency of primary corrosion and the rusting flow in the simulative marine atmosphere environment. By observing the corrosion evolution of surface microstructures and composition by the scanning electronic microscope (SEM) and the energy dispersive spectrometer (EDS) at the different stages, the corrosion mechanism was further discussed in details.
