| Abstract: |
| Ni nano-films were obtained by direct current electrodeposition. The effect of C12H24NaSO4, TJ and GL-100 on coating of micro-surface morphology, hardness, grain size and texture, and the relation of between current density and hardness were studied. The results indicate that the growth rate and direction of the crystal surface are changed, and the crystal plane(200)is occurred texture when the electro-bath is absence of additives or only join C12H24 NaSO4.The addition of TJ make the grain significant refainment. The coating grains prefer to grow with orientation in the crystal plane(111)when TJ and GL-100 are added in the electro-bath.Surface morphology and hardness of the coating achieve the best condition with adding three kinds of additives. On the same plating conditions, the coating hardness increases with the increasement of current density. |
