“…During diamond CVD deposition, metallic Ti reacted with carbon species and the ''skin'' of the droplets was transformed into thicker TiC. However, due to the low diffusivity of carbon in TiC [14], even after three hours of diamond deposition the cores of the droplets were still metallic. As a result, after diamond coating deposition the most intense Ti(101) peak could still be detected using XRD.…”

“…The formation of TiC at the bonded interface is possible and consistent with both theoretical thermodynamics and experimental data. [12][13][14][15] X-ray diffraction patterns for the extruded Ti composite materials reinforced with in situ formed TiC particles are shown in Fig. 4.…”

A powder metallurgy (P/M) titanium matrix composite (TMC) reinforced with low cost carbon black was prepared by spark plasma sintering (SPS) and hot extrusion. Carbon black particles were added for the in situ formation of TiC dispersoids during the SPS process. Two kinds of titanium (Ti) powders, sponge and fine Ti, were coated with carbon black particles via a wet process using a zwitterionic solution containing carbon black spheres. The distribution of the particles on the Ti powder surface before the consolidation process was imaged using scanning electron microscopy (SEM). We evaluated the microstructure and mechanical properties of extruded pure Ti matrix composites reinforced with TiC particles. The morphology and distribution of the in situ TiC phases were investigated using optical microscopy and SEM with the help of an EDS analyzer. The mechanical properties of these composites were remarkably improved by adding a small amount of carbon black at 0:07$0:16 mass%. The increases in the yield stress of the extruded sponge and fine TMC were 70.0 and 291 MPa, while the tensile strength increases were 67 and 231 MPa, respectively, compared to those of extruded pure Ti with no reinforcement. Finally, the fractured surfaces of TMC specimens after tensile testing were observed. The benefits of the wet process and the use of carbon black additives are discussed in detail.

“…All specimens were elaborated from a 400 mesh commercial titanium powder (purity: 99.9). The carbon fibrous reinforcement was chosen after trying Cu/W based diffusion barriers and studying carbon/titanium interaction at moderate temperatures [44,45]. From these studies, it has been concluded that artificially interposing a very thin continuous TiC layer between Ti and C would be the best solution for impeding the natural uncontrolled formation of angular crystallites of TiC.…”

“…In this direction and awaiting the availability of TiC coated C fibres yarns obtained by reactive CVD on a pyrolytic C pre-coating, FT500 carbon fibres coated by 40 nm of pyrolytic carbon were used (560 GPa of rigidity and 3610 MPa of strength). The aim of the C pre-coating was to protect the reinforcement from natural TiC formation which was expected to remain limited for the composites processing conditions [45].…”
