Preparation of Electroless Ni-Mo Coated TiC Powder

Abstract:

Article Preview

Ni-Mo coated TiC powders were prepared by electroless plating technique assisted by ultrasonic wave with hydrazine as reducing agent. The surface microstructure of the Ni-Mo coated TiC powders was characterized with scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and X-ray diffractometry (XRD). The results showed that the as-plated powders, which were of nearly spheric shape, were the composite of TiC and Ni-Mo alloy. The Ni and Mo elements were uniformly distributed around the TiC powders with some plating leakage. In addition, the Ni-Mo plated thin layers on the surface of TiC powders were amorphous or microcrystalline in a supersaturated state. Diffraction peaks corresponding to Ni and Mo weren’t found, and the Ti (NO3)4 and an unknown phase were formed as the load decreased from 15 g/L to 5 g/L.
