Abstract
The article presents the results of tests carried out on the manufactured composite materials based on a two-phase NiAl/Ni<sub>3</sub>Al matrix, which was enriched with the addition of TiB<sub>2</sub> ceramic particles added in an amount of 4 and 7 vol%. The resulting mixtures were sintered by the High Pressure High Temperature (HP-HT) process. The results were compared to the results obtained for the sole matrix material produced under the same conditions. It has been shown that, at a lower density, the addition of reinforcing particles increases the composite hardness, Young’s modulus and resistance to frictional wear. However, higher addition of TiB<sub>2</sub> (7 vol%) was observed to yield less satisfactory results, and despite higher hardness and lower density caused a decrease in other properties tested. The produced materials were characterized by a compact and highly differentiated microstructure free from any noticeable cracks and pores.
