| Abstract | The self-lubricating composites Ni3Al–BaF2– CaF2–Ag–Cr, which have varying fluoride contents, were fabricated by the powdermetallurgy technique. The effect of fluoride content on the mechanical and tribological proper- ties of the composites was investigated. The results showed that an optimal fluoride content and a balance between lubricity and mechanical strength were obtained. The Ni3Al–6.2BaF2–3.8CaF2–12.5Ag–10Cr composite showed the best friction coefficients (0.29–0.38) and wear rates (4.2 9 10-5 –2.19 9 10-4 mm3 N-1 m-1 ) at a wide tem- perature range (room temperature to 800 C). Fluorides exhibited a good reduced friction performance at 400 and 600 C. However, at 800 C, the formation of BaCrO4 on the worn surface due to the tribo-chemical reaction at high temperatures provided an excellent lubricating property. |
