It is found that the structure of Co-Ni deposits which were single phase solid solution composed by solvent Co and solute Ni is hexagonal close packed(hcp),while the structure of pure Ni deposits is face-centered cube(fcc).

• 结果表明,Co-Ni镀层是具有六方密排结构(hcp)的,以Co为溶剂,Ni溶解在Co中的单相固溶体,而纯Ni镀层为单一的面心立方结构(fcc)。
