| 摘 要： | 研究了电刷镀液中纳米Al2O3颗粒含量对复合镀层中纳米颗粒含量、镀层表面形貌、显微硬度以及摩擦学性能的影响。结果表明，随着镀液中纳米Al2O3颗粒含量的增加，镀层组织细化，显微硬度提高，镀层在含细沙油润滑条件下的耐磨性比不加纳米颗粒的快速镍镀层提高了80％。当镀液中Al2O3含量为20 g/L时，镀层具有最佳的耐磨性，进一步提高镀液中的纳米颗粒含量，镀层性能反而下降。

| Abstract: | The effects of nano -Al_2O_3 particle content in the electrolyte on the nano-particle content, microstructure, hardness and wear resistance of the composite coating were studied. The results show that the microstructure and hardness of the composite coating are improved with the increase of the nano-particles in the electrolyte, and the wear resistance of nano-composite coating is 80% higher than that of high speed nickel coating. The nano-composite coating has the best wear resistance when the nano-particle content in the electrolyte is 20 g/L, above which the wear resistance decreases. |

| Keywords: | composite coating nano-particles hardness wear resistance |
