PORBLEMS & SOLUTIONS IN DENSIFICATION OF W-Cu COMPOSITE

摘要: 在常规溶渗、烧结条件下金属钨和铜之间互不溶解，浸润特性能差，使两种粉末复合的致密化过程进行相对困难。阐述了如何提高该系统致密化过程和速度，弱化致密化条件，获得均匀弥散且两相分别连续分布的组织结构，并实现对成分和尺寸的准确控制。结合各类应用的性能要求，对钨铜复合材料致密化的各种方法进行分析和讨论，试图为选择高性能钨铜复合材料加工方法提供依据。

Abstract: It is rather difficult to densify W-Cu powders composite, due to the insolubility and poor wetting property between W and Cu. This paper will analyze and discuss several methods for enhancing densification, having regard to the performance requirement in application. Effort to establish foundation for producing W-Cu composite with high performance is given.
