本文论述了两种新的钨基复合材料。一种是“NDB”产品,该产品不是用铜焊法将W-Cu和铜基体接合,而是用浸渗和铸造法制成。我们成功的大量生产了在接合层没有缺陷的“NDB”产品。另一种是“NS-EMC”产品,这是一种用新的净形法(Net-Shape method)制成的W-Cu复合材料,制造该材料的高密度压块是由粗、中、细三种粒度的钨粉制得的,钨粉粗粒粒度大于制造常规W-Cu复合材料的粗粒粒度。因此我们解决了属于液相烧结的净形法所引起的问题。 This article discusses two new tungsten matrix composites. One is the “NDB” product, which is made by impregnation and casting instead of joining the W-Cu and the copper substrate by brazing. We have successfully mass-produced “NDB” products that are free from defects in the bonding layer. Another is the “NS-EMC” product, a W-Cu composite made with the new Net-Shape method. The high-density briquette made from this material consists of coarse, medium, Fine three particle size of tungsten powder, tungsten powder coarse particle size greater than conventional W-Cu composite material manufacturing coarse particle size. Therefore, we solved the problem caused by the net shape method that belongs to liquid phase sintering.
