Abstract
High-temperature self-lubricating nickel-alloy based composites with Ag and three amounts of BaF2/CaF2 eutectic were prepared by hot press sintering technique. Both the composites with 5 wt% and 10 wt% BaF2/CaF2 eutectic exhibited markedly higher strength than 15 wt% composite. The friction coefficient of the three composites was comparable. All three composites showed the highest wear rate at 600 °C, but very lower at 800 and 900 °C. The friction coefficient of the three composites was slightly lower as sliding against Si3N4 than Inconel 718. The friction and wear mechanism was proposed.
