本发明涉及一种制备纯钨金属零件的方法,该方法采用一定粒度的钨粉先施加振动,提高其初始相对密度之后,再进行模压及低温度烧结的方法制得了高温度烧结方法更高密度的超高纯金属零件。本发明方法能耗低,制备的钨金属零件更加致密、性能更高。

The invention relates to a method for preparing pure tungsten metal parts. The method adopts a certain particle size tungsten powder to first apply vibration to increase its initial relative density, and then perform molding and low-temperature sintering methods to obtain a high-temperature sintering method with higher density of ultra-high purity metal parts. The method of the invention has low energy consumption, and the prepared tungsten metal parts are denser and have higher performance.
