Synthesis and characterization of pulse co-electrodeposited nickel/ceria nanocomposites.
Nanocrystalline nickel matrix composites reinforced with the nanosized ceria particles have been synthesized by cathodic pulsed electrodeposition. The reinforcement is synthesized by the high energy ball milling (HEBM) technique. Both the reinforcement and composites have been characterized by XRD, TEM and SEM coupled with EDS. The microhardness of the composites containing different volume fractions of ceria have been evaluated and compared with that of pure nanocrystalline nickel deposited under the same conditions. The results show that the hardness of the composite is significantly higher than that of the nanocrystalline pure nickel.
