| Abstract: | Nano-Al_2O_3/Ni composite deposit was prepared by electrodeposition. The effects of current density and concentration of suspended n-Al_2O_3 powders on Al_2O_3 content and the hardness of the coating were studied. A gradient deposit of n-Al_2O_3 / Ni was prepared at a constant current density. The hardness of the coating increased with increase of the deposit thickness. Wear resistances of the gradient deposit increased to 150% compared with that of the traditional composite deposit in the condition of oil lubrication. |
