Abstract:
      In light of the common problem of hydrogen evolution in traditional electroforming nickel and the huge advantages of this new medium ionic liquid, the effects of temperature, current density on electroformed nickel’s morphology and structure as well as the tensile strength and microhardness of electroformed nickel from ionic liquid were first studied in this paper. The results show that the suitable temperature range are from 110 ℃ to 130 ℃. XRD tests show electroforming temperature can also significantly improve the degree of crystallinity of electroformed nickel layer, and promote the transformation of preferred orientation of grains from (111) to (200). 1 mA/cm2 is the best current density. With the increasing of it, the surface of Ni looks rougher and rougher, but grain size and the degree of crystallinity of Ni decreases. In addition, compared with aqueous solution, Ni electroformed from ionic liquid has higher tensile strength and microhardness.
