在这个工作,我们通过腐蚀测试在纯镁的腐蚀上在氯化物离子和白朊的 synergistic 效果上报导。我们证明白朊的吸附主要在 NaCl 答案影响纯镁的阳极的极化行为。白朊的低集中在起始的沉浸时间提高纯镁的反应反应和氢的起始的发展。1 g/L 白朊的增加在 NaCl 答案为纯镁提供有限腐蚀控制。与低集中白朊比较, 10 g/L 白朊的增加能有效地与 0.20.8 wt.% 的 NaCl 集中在测试答案禁止纯镁的进一步的溶解,但是这效果与增加氯化物离子的集中逐渐地降低。
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.
