The effect of different cathodic potentials applied to the X70 pipeline steel immersed in acidified and aerated synthetic soil solution under stress using a slow strain rate test (SSRT) and electrochemical impedance spectroscopy (EIS) was studied. According to SSRT results and the fracture surface analysis by scanning electron microscopy (SEM), the steel susceptibility to stress corrosion cracking (SCC) increased as the cathodic polarization increased (Ecp). This behavior is attributed to the an...

The work focuses on the analysis of electrochemical corrosion in synthetic salt medium of the TiC/Ni-20Cr composite through the polarization curve technique at four exposure times (0, 6, 12 and 24 h). The composite was prepared by liquid infiltration of the liquid alloy into a porous body of TiC. It was found a continuous and homogeneous distribution of the reinforcing material in the interconnected matrix, having a residual porosity of 6.49 vol.%. According to the electrochemical results, in bo...

In this paper corrosion kinetics was evaluated by Electrochemical Noise (EN) technique for carbon steel fasteners coated with nickel-cobalt (Ni-Co), immersed in synthetic seawater at 60°C and atmospheric pressure at Veracruz Harbor, Mexico. An electrochemical cell with a three electrode arrangement was used: two identical work electrodes and a reference electrode (saturated calomel electrode, SCE). An electrochemical study was performed to evaluate the applicability of this kind of materials in ...
