Effect of Electrolyte Concentration on Electrolyte Failure in Magnesium Alloy Micro-arc Oxidization

  • 摘要: 使用自制微弧氧化设备,在硅酸盐体系电解液中对镁合金进行微弧氧化试验。制备出了致密、光滑的陶瓷层。采用正交试验法研究了镁合金微弧氧化处理所用硅酸盐体系电解液中,SiO32-浓度、F-浓度和OH-浓度对电解液失效前最大处理面积的影响。研究表明:各离子浓度对镁合金微弧氧化最大处理面积有较大影响,影响程度按照大小次序排列分别是:OH-浓度>F-浓度>SiO32-浓度;最佳的电解液组成方案应该是OH-:7 g/L;F-:8 g/L;SiO32-:15 g/L。
    Abstract: A compact and smooth ceramic coat was prepared on the surface of magnesium alloy through micro-arc oxidation(MAO) treatment in silicate electrolyte with self-manufactured equipment.Effects of some factors,such as concentrations of SiO32-,F- and OH- on max treatment area before inactivation were investigated by orthogonal test.The results showed that concentrations of OH-,F- and SiO32- influence the max treatment area obviously in sequence OH-,F- and SiO32-.A optimized electrolyte composition should be OH-:7g/L;F-:8g/L;SiO32-:15g/L.
