| description | The invention discloses a method for improving wettability of rare earth oxide powder and a CuW alloy. The method comprises the steps that a certain amount of rare earth oxide powder of few nanometersto tens of micrometers is selected, the surface of the rare earth oxide powder is evenly wrapped with a layer or multiple layers of metal through surface treatment and wrapping to obtain metal/rare earth oxide powder microcells, and mixing, cold press molding, sintering and compacting composite sintering molding of the metal/rare earth oxide powder microcells and the CuW alloy are conducted. Therare earth oxide powder is subjected to surface treatment and wrapping, the metal/rare earth oxide powder microcells with good metal wettability and the metal material are obtained and doped, and themore excellent material performance is obtained. The method greatly avoids the problem that traditional CuW alloy doped with the rare earth oxide powder is not wet and difficult to form, the cost is low, and the industrial scal |
