原位阻抗谱研究$\beta$相对镁--铝合金初期大气腐蚀行为的作用
Keywords: 镁-铝合金,β相,大气腐蚀,电化学阻抗
Abstract:
？采用原位电化学阻抗(eis)技术研究了薄液膜条件下β相对镁铝合金初期腐蚀行为的影响。结果表明由nacl诱发的镁合金初期大气腐蚀,β相起到了关键作用。在早期的10h内,β相体积分数较多的镁合金对应阻抗谱的电荷转移电阻比较大,表明其腐蚀速率较慢,这是由于镁合金中β相相对耐蚀。但在高浓度cl-作用下,随暴露时间的延长,一旦突破合金表面β相的阻碍后电荷转移电阻明显下降,腐蚀速率加快。β相体积分数较少的镁合金随着暴露时间的延长,腐蚀产物膜的保护性明显优于β体积分数较多的镁合金,这有助于减缓β相体积分数较少的镁合金基体在暴露后期的腐蚀速率。
