In order to adapt to the development of lightweight equipment, and further improve the wear resistance of ZL109 aluminum alloy, the influence of nickel-coated carbon nanotubes as an electrolyte additive on the preparation and wear resistance of microarc oxidation ceramic coatings on ZL109 aluminum alloy surface was investigated. In this work, 0.4 g/L, 0.8 g/L, 1.2 g/L, 1.6 g/L, and 2 g/L nickel-coated carbon nanotubes were added to the electrolyte respectively. The microarc oxidation ceramic coatings were prepared under bipolar pulse constant pressure mode, which were analyzed from the aspects of morphology, chemical composition, and wear resistance property. The results show that the nickel-coated carbon nanotubes possess a great influence on ceramic coatings. The morphology of ceramic coatings was significantly changed. In this work, the coating prepared by 1.2 g/L nickel-coated carbon nanotubes exhibits excellent wear resistance property.
为了适应轻量化装备的发展，进一步提高ZL109铝合金的耐磨性，研究了镀镍碳纳米管作为电解液添加剂对ZL109铝合金表面微弧氧化陶瓷涂层制备及耐磨性的影响。在本工作中，分别向电解液中添加0.4 g/L、0.8 g/L、1.2 g/L、1.6 g/L和2 g/L的镀镍碳纳米管。在双极脉冲恒压模式下制备微弧氧化陶瓷涂层，并从形貌、化学成分和耐磨性能等方面进行分析。结果表明，镀镍碳纳米管对陶瓷涂层有很大影响。陶瓷涂层的形貌发生了显著变化。在本工作中，由1.2 g/L镀镍碳纳米管制备的涂层表现出优异的耐磨性能。
