| 中文摘要: |
| 采用复合电沉积技术在AZ91镁合金表面制备Ni-SiO2 纳米复合镀层,并研究各工艺参数对镀层的影响,从而得出最佳工艺。研究结果表明:在镀液中纳米SiO2 的添加量为20g/L,阴极电流密度为1.0A/dm2,镀液温度为50℃,活性剂A 的添加量为1.0g/L,pH 为5~6的条件下,经过20~30min电沉积,可获得均匀、平滑的镀层,镀层的显微硬度与耐蚀性最佳。 |
| 英文摘要: |
| The nano-sized Ni-SiO2 coating was prepared on AZ91 magnesium alloys by composite electroplating, and the effect of process parameter on the coating was studied and the optimum process was obtained. The results show that the surface of the coating is smooth and the coating posesses the best micro-hardness and corrosion resistance when the content of nano-sized SiO2 and activator is 20 g/L and 1 g/L in the electroplating bath with pH value 5~6, respectively, and the electrodepositing time is 20~30 min at 50℃ and the the cathodic current density is 1 A/dm2. |
