摘要：

Cr-Ni multilayers with thickness modulation of several tens of nanometers were prepared by pulse-current electroplating from a Cr(III)-Ni(II) bath at 30 degrees C. The Cr-Ni multilayers were composed of alternate amorphous Cr-rich and nanocrystalline Ni-rich layers. This amorphous Cr-rich layer could be attributed to a reduction in the complex-formed Cr ion, which leads, to the presence of C, a glass-forming element, in the Cr-rich deposit during electrodeposition. Twins were found in the nanosized Ni-rich layer, in which stacking faults were frequently observed. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
