“…However, the activation energies indicate that the same mechanism is operating in both alloys. Oxidation activation energies reported in the literature for Ti-6Al-4V and ␣-titanium with and without dispersoids range from 60 to 300 kJ/mol [20,21,[26][27][28][29]. The activation energies reported in this study are in the upper region of this range.…”

“…As key engineering materials, Ti alloys have found many important applications in a variety of industries including aerospace, energy generation, and biomedical areas because of their high specific strength and excellent corrosion resistance [1,2]. To further improve their mechanical properties such as wear resistance and high temperature durability, ceramic particles and/or whiskers were introduced into the Ti matrix [3][4][5]. However, traditional Ti matrix composites (TMCs) with a large percentage of ceramic reinforcements were usually accompanied by poor tensile ductility [4,6].…”

“…Moreover, when B 4 C was used as the precursor rather than B, TiB nanowires were still achieved together with TiC particles distributed along the network [12]. The TiC particles have also been widely introduced into Ti matrix as reinforcements, alone or together with TiB whiskers [4,5,14].…”

High-performance Ti-based nanocomposites reinforced with TiB nanowires with a network-woven structure were fabricated, and the growth of the TiB nanowires was investigated through comparative sintering and annealing experiments. TiB nanowires nucleated from the surfaces of the Ti powder particles and then grew into the particles. They remained stable in the Ti matrix when isothermally annealed at 1000 o C for 24 h, but coarsened noticeably during rapid heating to 1200 o C. The coarsening of the TiB nanowires was found to occur through stacking of thinner TiB nanowires, which can be regarded as a detachment-attachment controlled Ostwald ripening process and is

“…In order to obtain a synergy of useful properties that are beyond the reach of titanium and its alloys, titanium-based composites are used, in which the reinforcing phase and the matrix have been properly tailored. The particle reinforcement of titanium and its alloys provides the possibility of significant improvements in mechanical properties [ 1 , 2 , 3 , 4 ]. Generally, metal matrix composites are used in wear resistant applications, where high hardness combined with a reasonable level of toughness occurs [ 5 , 6 , 7 ].…”

This paper describes the microstructure and properties of titanium-based composites obtained as a result of a reactive spark plasma sintering of a mixture of titanium and nanostructured (Ti,Mo)C-type carbide in a carbon shell. Composites with different ceramic addition mass percentage (10 and 20 wt %) were produced. Effect of content of elemental carbon covering nc-(Ti,Mo)C reinforcing phase particles on the microstructure, mechanical, tribological, and corrosion properties of the titanium-based composites was investigated. The microstructural evolution, mechanical properties, and tribological behavior of the Ti + (Ti,Mo)C/C composites were evaluated using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), electron backscatter diffraction analysis (EBSD), X-ray photoelectron spectroscopy (XPS), 3D confocal laser scanning microscopy, nanoindentation, and ball-on-disk wear test. Moreover, corrosion resistance in a 3.5 wt % NaCl solution at RT were also investigated. It was found that the carbon content affected the tested properties. With the increase of carbon content from ca. 3 to 40 wt % in the (Ti,Mo)C/C reinforcing phase, an increase in the Young’s modulus, hardness, and fracture toughness of spark plasma sintered composites was observed. The results of abrasive and corrosive resistance tests were presented and compared with experimental data obtained for cp-Ti and Ti-6Al-4V alloy without the reinforcing phase. Moreover, it was found that an increase in the percentage of carbon increased the resistance to abrasive wear and to electrochemical corrosion of composites, measured by the relatively lower values of the friction coefficient and volume of wear and higher values of resistance polarization. This resistance results from the fact that a stable of TiO2 layer doped with MoO3 is formed on the surface of the composites. The results of experimental studies on the composites were compared with those obtained for cp-Ti and Ti-6Al-4V alloy without the reinforcing phase.
