Synergistic effect of chloride ion and albumin on the corrosion of pure magnesium

In this work, we report on synergistic effect of chloride ion and albumin on the corrosion of pure magnesium through corrosion tests. We show that the adsorption of albumin mainly affects the anodic polarization behavior of pure magnesium in NaCl solution. Low concentration of albumin enhances the r...

Description
Summary:In this work, we report on synergistic effect of chloride ion and albumin on the corrosion of pure magnesium through corrosion tests. We show that the adsorption of albumin mainly affects the anodic polarization behavior of pure magnesium in NaCl solution. Low concentration of albumin enhances the reaction reactivity of pure magnesium and the initial evolvement of hydrogen at the initial immersion time. Addition of I glL albumin provides limited corrosion control for pure magnesium in NaCl solution. In comparison with low concentration albumin, addition of 10 g/L albumin can effectively inhibit the further dissolution of pure magnesium in test solutions with NaCI concentration of 0.2-0.8 wt. %, but this effect lowers gradually with increasing the concentration of chloride ion.
