Effect of Additive on Microstructure and Property of Bulk Nanocrystalline Co-Ni Alloys Prepared by JED

Abstract:

The bulk nano-crystalline cobalt-nickel alloys have been prepared by the double refined methods (DRM) combined the high-speed jet electrodeposition (JED) with the additive added in jet electrolyte, and their microstructure and properties, such as the microhardness and magnetic properties, have been evaluated. The results indicate that the DRM is a very effective technique for grain size refinement and property improvement. The concentration of the additive added in the jet electrolyte has little effect on the Co-content in the deposited alloys, but they have a remarkable effect upon the microstructure and properties.
