| Research Abstract |
Super hard Ni-B/diamond composite coatings were prepared by wet methods. The coating of the first method was composed of electrophoretic deposition of diamond particles with electroless deposition of Ni-B matrix. The Vickers micro-hardness of the coating was 2,500 Hv after heat treatment. The coating of the second method was prepared by electrodeposition of Ni-B/diamond coating from Ni-B bath dispersing diamond particles. The micro-hardness of this coating was 2,300 Hv after heat treatment. The formations of super hard coatings were ascribed to the hardness of diamond and Ni-B matrix.
