摘要
研究了微量添加剂WO3对Ag/TiB2复合材料组织和性能的影响,采用扫描电子显微镜对Ag/TiB2复合材料的组织进行了表征,对硬度和电导率进行了测试。结果表明,WO3改善了复合材料的烧结性能和TiB2在Ag基体上的分布。与未添加Ag/TiB2复合材料相比,添加1.0%(质量分数)WO3后,Ag/TiB2复合材料的密度、硬度和电导率分别提高了8.0%、10.0%和47.0%,而且材料的塑性有所改善。
The effect of WO3 addition on the microstructure and properties was investigated.The microstructure of Ag/TiB2 composite with additives was characterized by a scanning electron microscope,and the hardness and electrical conductivity were tested.The results show that WO3 can improve the sintered performance and the distribution of TiB2 in Ag matrix.In comparison with those of Ag/TiB2 composite without any additive,the density,hardness and electrical conductivity of Ag/TiB2 composite with 1.0wt% WO3 addition are increased by 8.0%,10.0% and 47.0%,respectively,WO3 addition can improve the plasticity of Ag/TiB2 composite as well.
