Influence of ▫$TiB_2$▫ and wear conditions on friction and wear behaviour of SiC ceramics in reciprocating sliding

Prakasarao, Chodisetti Surya (avtor), Kalin, Mitjan (avtor), Kumar, B. V. Manoj (avtor)

Friction and wear characteristics of spark plasma sintered SiC-▫$TiB_2$▫ composites in reciprocating sliding contacts are evaluated in terms of ▫$TiB_2$▫ content (0 - 30 vol%), normal load (5, 10 and 15 N) and temperature (25 °C and 600 °C). With increase in TiB2 content, friction increased, and wear decreased. Scanning electron microscopy, atomic force microscopy and Raman spectroscopy studies confirm protective tribo-oxidation in sliding at 600 °C. Effect of wear debris on friction response and wear resistance is emphasised. Wear mechanisms changed from fracture at 25 °C to tribo-oxidation at 600 °C. The presence of ▫$TiB_2$▫ reinforcement helps in enhancing wear resistance of SiC ceramics at room temperature, while formation of oxide layer and cylindrical debris are responsible for less wear at 600 °C.
