Effect of temperature on corrosion behavior of E690 steel in 3.5 wt.% NaCl solution
نویسندگان
چکیده
Abstract The corrosion behavior of E690 steel in 3.5 wt.% NaCl solution at temperatures from 20 °C to 60 was investigated using electrochemical test. morphology characterized SEM and AFM, the layer EDS, Raman spectroscopy XPS. results showed that rate improves with increase temperature. layers are mainly composed α -Fe 2 O 3 , -FeOOH γ -FeOOH. With elevated temperature, content increases, while decreases. mechanisms were briefly discussed.

Comparison of Medium Manganese Steel and Q345 Steel on Corrosion Behavior in a 3.5 wt % NaCl Solution
A cyclic wet/dry accelerated corrosion test was used to compare the corrosion behavior of medium-Mn steel and Q345 steel. In terms of scanning electron microscope (SEM), using X-ray diffraction (XRD), electron probe microanalysis (EPMA), X-ray photoelectron spectroscopy (XPS), and analysis of the corrosion process, the results showed that the medium-Mn steel did not exhibit higher corrosion res...
