Although Ti-based composites find wide industrial applications, their tribological behaviour, especially at elevated and high temperatures, is not conclusively evaluated. In this work, a sliding wear performance of metal – ceramic composite of 50 wt%Ti–50 wt%TiB_w, which were in-situ produced by spark plasma sintering, was studied. Microstructural examination and X-ray diffraction analysis identified presence of two phases, Ti and TiB, and confirmed the formation of stable TiB whiskers-like grains (TiB_w) during reaction synthesis of Ti and TiB₂. Ball-on-plate dry sliding wear tests were performed against a 10 mm alumina ball under 5 N normal load with the sliding speed and distance of 0.1 ms⁻¹ and 1000 m, respectively. The tests were performed at RT and elevated temperatures of 300 °C, 500 °C, 700 °C, 800 °C and 900 °C. The worn surfaces were studied using scanning electron microscopy and 3D profilometry to understand the responsible wear mechanisms. Results have demonstrated significantly reduced wear rates of Ti-TiB_w composite as compared to reference pure Ti across all temperatures. The formation and the protective role of tribo-oxide layers on the surface of Ti-TiB_w composite during elevated temperature sliding is reported.
