关键字：jet electrodeposition multilayer films modulation period microhardness wear resistance
摘要：In the following paper, Cu-Ni multilayer films were prepared by rotating jet electrodeposition (RJE). The Cu plating solution and the Ni plating solution were sprayed alternately during deposition to the rotating cathode surface through the corresponding nozzle. The cross-sectional morphology, microstructure, microhardness, and wear resistance of multilayer films were measured by scanning electron microscope, X-ray diffractometer, microhardness tester, and depth of field microscope, respectively. The results revealed that this novel method had no limit to the technological conditions and avoided the oxidation of the films which existed within the preparation of multilayer films by conventional electrodeposition. The sublayer boundaries of the obtained multilayer films were clear. A semi-coherent interface was formed between the sublayers. The resulting special structure reinforced the properties of the films. The microhardness of the multilayer films increased as the modulation period decreased. When the modulation period was reduced to less than 100 nm, the hardness increased dramatically. In addition, the wear resistance of multilayer films was improved when the modulation period decreased.
