摘要:
利用电沉积方法制备了n–Al2O3/Ni复合镀层。研究了镀液中添加不同纳米颗粒浓度对复合镀层沉积速率、电流效率、镀层中纳米颗粒共析量、表面形貌及腐蚀电位的影响。研究表明，随着镀液中纳米颗粒浓度提高，镀层中的纳米颗粒共析量也随之提高，在20 g/L时趋于稳定；沉积速度和电流效率先增后降，在30 g/L时达到最大；纳米颗粒的加入改变并细化了镀层的表面形貌；当纳米颗粒浓度20 g/L和30 g/L时镀层表现出较好的耐腐蚀性能。

Abstract:
A composite electro-deposited coating of n–Al2O3/Ni was prepared. The effects of concentration of suspended n–Al2O3 powders on the deposition process were studied. The results showed that nano-particle content in the deposit increased with raising the nano-particle concentration in the solution and stabilized at 20 g/L. Deposition rate and current efficiency increased at first and decreased later，and up to maximum at the content of 30 g/L. The surface morphology was changed and refined by nano-particle. The composite coating showed better resistant to corrosion at the nano-particle content of 20 g/L and 30 g/L.
