| Abstract: | The microstructure of X80 pipeline steel welding joint,consisted of Fe_3C and degenerated pearlite,was simulated by carburizing treatment.The effects of Fe_3C and pearlite on the electrochemical properties of bainitic ferrite steel and localized corrosion occurrence regularity in Yingtan soil simulation solution were investigated by scanning Kelvin probe(SKP),scanning vibrating probe(SVP) and local electrochemical impedance spectroscopy(LEIS),combined with immersion test.It is demonstrated that the corrosio... |
