| 摘 要： | 通过在硅酸盐电解液中加入TiO2纳米添加剂,研究纳米添加剂浓度的变化对6063铝合金微弧氧化陶瓷涂层性能的影响。结果表明,纳米添加剂进入到陶瓷涂层中,而添加剂浓度的选取有一个较合理的范围。随着纳米添加剂的浓度增加到3.2g/L,涂层的结合力逐渐增大,平均摩擦因数和质量损耗逐渐减小。当浓度增加到4.0g/L时,涂层的结合力减弱,而平均摩擦因数增加,这与涂层显微硬度的测试结果一致。

| Abstract: | Ceramic coatings were fabricated on aluminum alloy substrates by micro-arc oxidation (MAO) in silicate electrolytes doped with different concentrations of TiO2 nano-additive. Effects of nano-additive concentration on the structural and mechanical properties of the MAO coatings were analyzed. The results revealed that some nano-particle were incorporated into the resulting coating during the MAO process, while there was a reasonable concentration for the TiO2 nano-additive. With increasing the nano-additive concentration to 3.2 g/L, the adhesion value increased, while mean friction coefficient and mass loss decreased. A further increase of nano-additive deteriorated the adhesion and mean friction coefficient values, which was consistent with the micro-hardness tests. |
