W-Cu Nano-Composite Powders Prepared by Hydrothermal Method

Article Preview

Abstract:

The grain size of W-Cu nanocomposites would greatly affect the density of W-Cu alloy. In this work, W-Cu oxide nanocomposite powders were prepared by sodium tungstate and copper nitrate via hydrothermal method, and W-Cu nanocomposite powders were obtained by subsequently co-reduction process. The characterization of W-Cu nanocomposite powders were carried out by X-ray diffraction (XRD), scanning electron microscope (SEM), energy spectrum analysis (EDS) and transmission electron microscope (TEM). The results indicated that hydrothermal method was a good method for the preparation of W-Cu oxide nanocomposite powders. W-Cu nanocomposite powders, whose grain size was about 70nm and distributed uniformity, were manufactured by co-reduction process.
