摘要: The present work is concerned with the study of activation mechanism Al in alloys produced by indium. electrochemical behaviour aluminium NaCl solutions containing In 3+ ions and dissolution Al-In In-Al were studied using potentiostatic, galvanostatic potentiodynamic techniques, complemented SEM. It was concluded that obtained only when indium comes into a true metallic contact within an active pit presence chloride ions. Polarization curves for compared. results suggest initial step alloy can be interpreted through ion adsorption on surface alloy. This occurs at more electronegative potentials than pure aluminium, thus avoiding repassivation.
