对镁一铝合金β相模型合金在不同浓度的CI一溶液环境中的腐蚀电化学行为进行研究,结果表明,随着Cl-浓度的增加,β相的自腐蚀电位依次降低.但β相与α相之间的电位差没有随Cl-浓度的增加递增.β相在不同浓度的C1-溶液中均能发生钝化,随Cl-浓度的增加点蚀击破电位降低,相应表面膜中含Mg的腐蚀产物种类也增多,在不同浓度Cl-溶液环境中,β相模型合金的腐蚀电化学结果可以揭示β相的微电偶作用 |

The electrochemical behavior of a modei p phase Mg-Al alloy was investigated in solutions with different concentrations of Cl-in comparison with model α phase alloy. The results indicated that the increase of Cl-concentration may decrease the corrosion potential of p phase. However, there is no distinct in potential difference between β phase and α phase. The β phase may be passivated in solutions with different concentrations of Cl-. With the increasing of Clconcentration the pitting breakdown potential of p phase slightly lower. There is excess Cl-doping the formed corrosion scales on β phase surface as the Cl-concentration increases. It is expected that β phase in magnesium-aluminum alloy may play certain role in micro galvanic couple with substrate in atmosphere corrosion in sodium chloride polluted environments |
