The present work reported a novel way of making nanocrystalline Ti-B phases (titanium boride and titanium diboride) in a hypersonic plasma jet. According to the purpose to synthesize nanosized Ti-B phases, experiments with different mass proportions of precursors were implemented. The optimal ratio of precursors, which leads to the yield of titanium diboride is 93.2% and the average particle size, doesn`t exceed 56.1 nm, is the ratio of Ti: B of 26.7: 73.3.

Microstructural change of TiB2-Cu nanocomposite during spark plasma sintering (SPS) was investigated. Under simultaneous action of pressure, temperature and pulse electric current titanium diboride nanoparticles distributed in copper matrix move, agglomerate and form a interpenetrating phase composite with a fine-grained skeleton. Increase of SPS temperatures and holding times promotes the densification of sintered compacts due to local melting of copper matrix.

Titanium diboride (TiB2) particles are most popular reinforcement along with tungsten carbide for ferrous matrices for developing composites with high specific modulus, improved wear resistance and hardness while providing good fatigue properties as well. The hardness of such composites poses a problem in conventional machining in terms of very fast wear rates of tools and very high cutting forces. Non-conventional processes like electrical discharge machining (EDM) are very popular for machining of conductive composites like TiB2 reinforced ferrous matrix composites. However, there are a large number of process parameters for EDM which need to be selected and controlled carefully for satisfactory machining performance. Parameter settings which lead to arcing are specifically investigated and avoided as this phenomenon leads to uncontrolled machining through short circuit conditions and large energy discharges. In this paper, an experimental approach to determine the parameter settings which will lead to arcing during EDM machining of TiB2 particulate reinforced ferrous matrix composite is discussed. Values of major EDM process parameters are selected in roughing, intermediate and finishing domains. Experimental trials using L27 design of experiment are conducted and parameter combinations leading to arcing are recorded and the zone of parameters that can lead to arcing is identified.
