EFFECT OF PB ADDITIONS ON THE FRICTION AND WEAR OF SINTERED FE-CU-SN-MOS2

Using conventional P/M techniques a new iron based antifriction materi al 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 degrees C for 20-50min. If was fo und that samples containing 7.5w/o Pb sintered at 850 degrees C for 30 min exhibited the lowest friction coefficients (0.13, 0.08 and 0.12) a nd wear rates (0.77 x 10(-9), 2.82 x 10(-9) and 6.18 x 10(-9) mm(3)/m) at PV values of 0.58, 0.76 and 2.68MPa m/s respectively and a hardnes s level of 254VHN.
