Results showed that there is a clear interface between Ni Cu and Cu layers, and every sublayer is homogeneous and continuous with good periodicity in this multilayers. The Ni Cu 4.6nm /Cu 1.4nm exhibits superlattice structure with epitaxial growth and has very different anodic behavior, specially showing strong corrision resistent properties. 电沉积 Ni－Cu／Cu 超晶格 多层膜 electrodeposition Ni Cu/Cu superlattice multilayers O484.5;O646.542 国家自然科学基金(61672102) 1998-06-01 2021-04-01 6
