摘要：In this work, the surface morphology and chemical analysis of carbon steel substrates after weight loss measurements in 1 M HCl media in the absence and the presence of aminotris-(methylenephosphonic) acid (ATMP) were studied using a scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). X-ray photoelectron spectroscopy was coupled to these characterizations to qualify corrosion layers and morphologies. The solution of immersion was analyzed by inductively coupled plasma. Results indicate that the addition of ATMP reduces the rate of metal attack. EDX, SEM and X-ray photoelectron spectroscopy observations of the electrode surface confirmed existence of a protective adsorbed film of the inhibitor on the electrode surface
