Abstract
- Abstract: ZrO2 (Y2O3) with different contents of BaF2/CaF2 and Mo were fabricated by hot pressed sintering, and the tribological behavior of the composites against SiC ceramic was investigated from room temperature to 1000°C. It was found that the ZrO2 (Y2O3)–5BaF2/CaF2–10Mo composite possessed excellent self-lubricating and anti-wear properties. The low friction and wear were attributed to enhanced matrix and BaMoO4 formed on the worn surfaces. [Copyright &y& Elsevier]
