Corrosion Electrochemical Characteristics of X80 Pipeline Steel in Southwest Area Soil

Abstract: The corrosion electrochemical characteristics of X80 pipeline steel was investigated in southwest area soil with saturated water using electrochemical measurement,scanning electron microscopy(SEM) and energy dispersive spectrum(EDS) analysis.The results show that the corrosion rate of X80 steel slowly increase and is controlled by oxygen diffusion process with extend of corrosion time.The characters of double capacitive reactance arcs and Warburg impedance could be found in electrochemical impedance spectra,the resistance of charge transfer and binding layer resistance decrease.The corrosion product is basically mixture of iron oxides and salts in soil.

Electrochemical impedance spectroscopy of sand of varied particle size and water content using the three-electrode system

Abstract: The EIS behavior, corrosiveness, and seepage structure of sand of varied water content were studied by means of electrochemical impedance spectroscopy under the three-electrode system. The...
