“…The XPS analysis was conducted at 400 W and a pass energy of 29.4 eV, using Al-Ka radiation as the exciting Table 1 provides the mechanical properties of the PM NiAl matrix self-lubricating composite. The Vicker's microhardness of the composite was higher than that reported by Murakami et al [19], possibly due to the addition of Cr and Mo, as were the yield stress and compressive strength. Figure 1a shows the microstructure of the sintered NCF composite.…”

A high-temperature self-lubricating composite NiAl-Cr-Mo-CaF 2 was fabricated using the powder metallurgy technique, and the tribological behavior of the composite at a wide range of temperatures (room temperature to 1000°C) was investigated. The results showed that the composite had a favorable friction coefficient of about 0.2 and an excellent wear resistance of about 1 9 10 -5 mm 3 N -1 m -1 at the high temperatures tested (800 and 1000°C). The excellent self-lubricating performance was attributed to the formation of the glaze film on the worn surface consisting mainly of CaCrO 4 and CaMoO 4 as high-temperature solid lubricants.

“…Molybdenum disulfide (MoS 2 ), graphite, soft noble metals (Au, Ag), metal oxides (Ag 2 O, Cu 2 O) and inorganic fluorides (CaF 2 , BaF 2 , BaF 2 /CaF 2 eutectic) have been explored as high-temperature solid lubricants [1][2][3][4][5][6][7]. A series of self-lubricating ZrO 2 (Y 2 O 3 ) matrix composites based on these solid lubricants were developed by powder metallurgy or plasma spraying methods [8][9][10][11][12].…”

Self-lubricating ZrO 2 (Y 2 O 3 )-Al 2 O 3 -Ba x Sr 1-x SO 4 (x = 0.25, 0.5, 0.75) composites have been fabricated by spark plasma sintering (SPS) method. The tribological properties have been evaluated using a high-temperature friction and wear tester at room temperature and 760°C in dry sliding against alumina ball. The composites exhibit distinct improvements in effectively reducing friction and wear, as compared to the unmodified ZrO 2 (Y 2 O 3 )-Al 2 O 3 ceramics. The ZrO 2 (Y 2 O 3 )-Al 2 O 3 -Ba x Sr 1-x SO 4 (x = 0.25, 0.5, 0.75) composites have great low and stable friction coefficients of less than 0.15 and wear rates in the order of 10 -6 mm 3 /Nm at 760°C. Delamination is considered as the dominating wear mechanism of the composites at room temperature. At elevated temperature, the formation and effective spreading of Ba x Sr 1-x SO 4 (x = 0.25, 0.5, 0.75) lubricating films during sliding play an important role in the reduction of the friction and wear.
