“…4,5) This composition-modulated Co-Ni laminated plating is available to produce by periodically varying stirring conditions during film formation in a single bath. Many of the studies [6][7][8][9][10][11][12] have been reported on the plating films consisted of the conventional metal multilayer films, but laminated structure producing required lamination in the plural different tanks or pulse electric plating as well as due to complicated manufacturing process, so that they are difficult to be put into industrial practice. In addition, there are many studies on the thickness of the constituent layers at the nanometer level, but there are few reports on thick films laminated with micrometer-level layers.…”

To improve the wear resistance of Ni/Cu multilayer films, Ni and Cu layers were electrochemically formed by applying multi-constant current pulse. The wear resistance of Ni/Cu multilayers was improved with the increase in the number of pulses which can cause thin Cu layer formation during Ni deposition. The cross-sectional observation of the Ni/Cu multilayer samples with SEM and TEM, and XRD measurement indicated that the reason for the improvement of the wear resistance of Ni/Cu multilayer films prepared with multi-constant current pulse is because smaller Ni/Cu multilayer structure was formed in Ni layer of the Ni/Cu multilayer and because Ni layer was constructed with smaller crystals with increasing in the number of pulse.

Synopsis : A composition-modulated Co-Ni laminated plating has been developed to extend the lifetime of molds used for continuous steel casting. We have investigated the relationship between the laminated structure and the mechanical properties of the plating films. The tensile strength of as-plated film increased with increasing thickness of the constituent layers, while the elongation did not depend on the thickness of the constituent layer and remained almost constant in the range from 3 to 5%. Heat treated at 400°C improved the tensile strength and the elongation. The improvement in the elongation was remarkable, and the elongation reached 13% in the film composed of layers with a thickness of 0.8 µm. The layer with low Ni content had an hcp structure, and that with high Ni content comprised two phases of the hcp and fcc structures in the as-plated state. By the heat treatment, the high Ni-content layer turned into the single fcc phase, while the low Ni-content layer kept the hcp phase, and accordingly, the film structure changed into the one where the lamination of the hcp and fcc layers was distinct. The fact that the fcc layers, which was easily deformed, were formed continuously in the lateral direction, was seemed to contribute to the significant improvement in the elongation after heat treatment.
