| 摘 要： | 采用阳极氧化技术提高镁一锂合金的耐蚀性.使用一种无铬环保型碱性电解液得到了有一定耐蚀性的白色氧化膜.用正交实验优选了电解液中三种组分的质量浓度;用扫描电镜分析了氧化膜表面形貌;用极化曲线研究了氧化膜的电化学腐蚀行为.结果表明:当电解液组成为NaOH 50 g/L,Na2SiO3·9H20 40 g/L,Na2B47·10H2O 30 g/L,Na3C6H5O7·2H2O 40g/L时,获得的阳极氧化膜的耐蚀性最好.EDS和XRD分析表明:氧化膜主要是由MgO,MgCO3两相组成.

| Abstract: | It has been investigated to use anodizing technology to improve the corrosion resistance of Mg-Li alloy.A white anodizing film with a certain corrosion resistance was obtained by using a kind of environmentally friendly chrome-free alkaline electrolyte.The orthogonal test on optimal mass concentrations of three compositions in electrolyte solution was conducted;the results of SEM indicate that different morphologies are observed on the covered surface of various process treated samples;the results of polari... |
