Research of Characteristics of Ni-W-P Nanocomposites Containing CeO₂ and SiO₂ Particles

Abstract:

Ni-W-P-CeO2-SiO2 nanocomposites were pulse electrodeposited from the bath containing suspension of nano-sized CeO2 and SiO2 particles. The influence of heat treatment temperature on the structures and properties were studied. The phase structures, surface morphologies, microhardness and oxidation behavior were evaluated by XRD, SEM, microhardness and oxidation weight gain test. Additionally, the sequence of phase transformation of the nanocomposites was found to be as follows: amorphous phase→intermediate metastable→stable alloy phase. Nano-particles co-deposited into Ni-W-P alloy can inhabit the grains growth, increase microhadness and high temperature oxidation resistance during the course of heat treatment.
