抄録

Bulk nanocrystalline Ni (nc-Ni) was electrodeposited using a sulfamate bath with different gloss agents. Saccharin sodium, 2-butyne-1,4-diol and sodium allylsulfonate, which were popular gloss agents for Ni plating, were chosen as gloss agents. Mechanical properties were evaluated to investigate the influence of gloss agent types on tensile properties in electrodeposited bulk nc-Ni. Results showed that gloss agent types strongly affect grain size, microhardness, and tensile properties of bulk nc-Ni. All bulk nc-Ni prepared using the sulfamate bath with gloss agents had a more refined grain size and higher microhardness than that prepared using a sulfamate bath without gloss agents. Particularly, bulk nc-Ni exhibited microhardness of greater than 700 Hv, when 2-butyne-1,4-diol was added to the bath. The tensile properties of bulk nc-Ni show different trends according to gloss agent types. When 2-butyne-1,4-diol was added to the bath, bulk nc-Ni exhibited no plastic deformation. Bulk nc-Ni obtained from sulfamate bath with saccharin sodium showed superior tensile ductility of greater than 10%. Bulk nc-Ni obtained from the sulfamate bath with sodium allylsulfonate exhibited high tensile strength of 1.8 GPa. These results suggest that bulk nc-Ni with different tensile properties can be prepared by choosing gloss agents.
