Adipic-sulfuric acid anodizing for LY12CZ aluminum alloy

  • 摘要: 通过向硫酸阳极氧化槽液中添加己二酸,研究了LY12CZ铝合金的己二酸硫酸阳极氧化,并与传统硫酸阳极氧化进行了对比.采用场发射扫描电子显微镜(FE-SEM)对两种阳极氧化膜的微观形貌进行了观察,用电化学阻抗谱(EIS)对比研究了两种氧化膜的电化学特性参数及耐腐蚀性能,采用万能力学实验机对阳极氧化后LY12CZ板材试样进行疲劳寿命测试比较.结果表明,与传统硫酸阳极氧化膜相比,己二酸硫酸阳极氧化膜具有更小的孔洞结构和更少的缺陷,在腐蚀环境中有更好的稳定性和耐腐蚀性能,对铝合金试样的疲劳损伤也大大减弱,并对机理进行了初步探讨.
