Electrochemical deposition and magnetic properties of Co-Ni alloys

Abstract

Co-Ni alloys including face-centered-cubic(fcc) and hexagonal closed-packed(hcp) were produced by using potentiostatical electrodeposition and pulse voltage electrodeposition in a three-electrode cell at room temperature.The produced fcc and hcp Co-Ni alloys were characterized by XRD,SEM,and EDX.The magnetic properties of the alloys were detected by using a vibrating sample magnetometer.Compared with Co-Ni-1 produced by using potentiostatical electrodeposition,the Co-Ni alloys produced by using the pulse voltage electrodeposition exhibited better compact nanostructures with higher Co molar ratio.
