Oil impregnated self lubricating bronze bearings were prepared by power metallurgy ( PM) method
with the mixed powder of 90wt%Cu and 10wt%Sn, and the bronze powder with 10wt% Sn content respectively. The microstructure and phase of the prepared bearings were investigated. The effects of sintering temperature on the Vick ers micro hardness (HV), radical crushing strength and oil content of the bearings were studied as well. It can be found that HV,radical crushing strength and oil content of the bearings have close connection with the sintering tem perature. Better pore structure and combined properties can be obtained for the bearings prepared with the mixed pow der compared with the bronze powder under the sintering temerature <780益.
