摘要: Abstract Corrosion inhibition of J55 steel in 3.5 wt.% NaCl solution saturated with CO2 by the three Porphines 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine (P1), 5,10,15,20-Tetraphenyl-21H,23H-porphine (P2), 5,10,15,20-Tetrakis(4-hydroxyphenyl)-21H,23H-porphine (P3), electrochemical impedance spectroscopy (EIS), Contact angle measurement, scanning microscopy (SECM), and atomic force (AFM). Adsorption such on surface obeyed to Langmuir adsorption isotherm. Atomic (AFM), SECM, results confirm formation inhibitor film thereby mitigating corrosion.
