中文摘要:
      采用电刷镀技术制备了不同Al2O3颗粒含量的合金纳米复合电刷镀层,采用扫描电镜、硬度测试仪和摩擦磨损试验机测试了纳米Al2O3颗粒含量对镀层的组织和性能的影响。结果表明,随着镀液中纳米Al2O3颗粒含量的增加,电刷镀层沉积速度降低、表面形貌平整,显微硬度先提高而后减低,磨痕深度先减小后增大,摩擦系数先减小后增大。当镀液中纳米Al2O3含量为20g/L时,镀层具有最优的组织和性能。

英文摘要:
      The composite electronic brush plating technique is facilitated to prepare the alloy nanocomposite plating with different nano-Al2O3 particles content. The effects of nanoparticles content in the electrolyte on the deposition rate, nanoparticles content, microhardness and tribological property of composite coatings are mainly discussed, measured by scanning electron microscopy, microhardness tester and attrition testing machine. It is found that, with the increase of nano-Al2O3 particles content in the solution, the deposition rate of coatings drops, the surface morphology of plating becomes flat, the microhardness is firstly enlarged and then decreased,wear scar depth is firstly reduced and then increased, friction coefficient is firstly reduced and then improved. When the nano-Al2O3 particles concentration in the electrolyte is 20g/L, the coating reaches its optimized structure and performance.
