Effect of PB additions on the friction and wear of sintered FE-Cu-SN-MoS<inf>2</inf>

Using conventional P/M techniques a new iron based antifriction material containing Cu, Sn, Pb and MoS2 has been developed in order to meet specific working conditions. Samples with Pb additions in the range of 0-12.5w /o have been sintered at 850°C for 20-50min. It was found that samples containing 7.5w/o Pb sintered at 850°C for 30min exhibited the lowest friction coefficients (0.13, 0.08 and 0.12) and wear rates (0.77 × 10-9, 2.82 × 10-9 and 6.18 × 10-9 mm3/m) at PV values of 0.58, 0.76 and 2.68MPa m/s respectively and a hardness level of 254VHN.
