Fabrication of W2NiB2-Ni Borides Cermets

Abstract

This study focuses on the criteria for the fabrication of W2NiB2-Ni boride cermets using W, Ni and B elemental powders. Their sintering behaviors and characteristics were examined in relation with compositions and sintering temperatures. The W2NiB2 boride particles were formed by the diffusion and reaction during sintering. It seems to be a easy way to develop the boride cermets such as W2NiB2-Ni cermets.
