INFLUENCE OF Ni CONTENT ON TiC Ni CERMETS BY SHS/PHIP

Densified TiC-Ni cermets were produced by SHS/PHIP. Theoretical analysis and experiments show that T ad and T c decrease with Ni increasing, combustion temperature influences the morphology of the products, and TiC particles become smaller and tend to be regular sphere when Ni content is increased. The products consist of TiC phase and Ni binder. Relative density gets higher with the increase of Ni content. Two factors determine the value of products hardness, and a maximum value of HRA appears at 20 wt% Ni.
