Research paper thumbnail of Effects of Copper Content and Ni Activator on the Densification of W-Cu Composite via Infiltration Process

International Journal of Science and Research (IJSR), 2016

In this study, a Tungsten porous substrate was prepared with cold uniaxial pressing. The results show that 25 Wt% Cu is the maximum cupper content that can be infiltrated. In order to enhance the composites properties, Ni has been added as activator of W matrix. In this case, it was found that (W-5Wt%Ni)-25Wt% Cu gives the most interesting result in terms of density, hardness and microstructure.
