Abstract

Electrophoretic deposition (EPD) was applied to the fabrication of nanostructured Ni-WC-Co composite coatings on nickel-plated stainless steel substrates. The micro-hardness and ball-on-disk sliding wear of the sintered composite coatings were tested for, and the results correlated to those of the microstructure analysis, which was determined by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Sintering after EPD on the substrates and high-pressure pressing resulted in dense composite coatings containing high volume fractional of nanostructured WC or WC-Co particles. Compared with pure nickel coatings or stainless steel, the coatings containing nanostructured WC-Co particles showed a significant increase in hardness and wear resistance. The remarkable improvement in hardness and wear resistance is attributed to the dispersion hardening of nanostructured WC-Co particles in the composite coatings.
