Electrodeposition and Thermal Treatment of Nickel Coatings Containing Cobalt

Abstract:

The Ni-P and Ni-Co-P coatings were electrodeposited at the deposition current density of j_dep = -20 mA cm^-2. Thermal treatment of these coatings was conducted in air at 400^oC for 1 h. Scanning electron microscopy (SEM) was used for surface morphology characterization of the coatings. Phase composition was investigated by X-ray diffraction (XRD) method. Atomic absorption spectrometry (AAS) was applied to specify chemical composition of obtained coatings. It was found that introduction of Co into amorphous Ni matrix caused the surface development of the obtained deposit. The Ni-P coating revealed an amorphous structure. The Ni-Co-P coating was formed of the amorphous matrix and the amorphous alloy ingredient. Thermal treatment of the coatings allowed to obtain new multi-phase materials with slightly developed surface.
