摘　　要：使用电泳技术在汽车用铜材表面沉积了氧化铝纳米膜。研究了纳米氧化铝的质量浓度对氧化铝纳米膜的沉积速率、表面形貌、显微硬度及耐蚀性的影响。结果表明:提高纳米氧化铝的质量浓度,有利于加快氧化铝纳米膜的沉积速率;当纳米氧化铝的质量浓度为8 g/L时,氧化铝纳米膜的表面质量最佳,显微硬度最大,耐蚀性最强。Alumina nano-films were deposited on the surface of copper materials for automobile by electrophoresis deposition. The influence of the mass concentration of nano-alumina on the deposition rate, surface morphology, microhardness and corrosion resistance of alumina nano-films was studied. The results showed that increasing the mass concentration of nano-alumina was beneficial to improve the deposition rate of alumina nano-films. The alumina nano-films prepared with 8 g/L nano-alumina exhibited the best surface quality, the maximum microhardness and the best corrosion resistance.
