Preparation and Properties of Ni-TiB₂-Gd₂O₃ Composite Coatings by Electrodepositon

Abstract:

Ni-TiB2-Gd2O3 composite coatings were prepared by electrodeposition method from a nickel cetyltrimethylammonium bromide and hexadecylpyridinium bromide solution containing TiB2 and Gd2O3 particles. The composite coatings were characterized with X-ray diffraction (XRD), atomic emission spectrometer (ICP-AES), scanning electron microcopy (SEM) and energy- dispersive analyses of X-ray (EDAX), respectively. That the codesposition of TiB2 and Gd2O3 into the coatings were demonstrated by XRD, EDAX, ICP-AES and SEM. TiB2 and Gd2O3 entered the lattice of Ni. The incorporation of TiB2 and Gd2O3 particles in the matrix can largely reduce the wear of the nickel composite coatings.
