Abstract: PURPOSE: To provide the graphite dispersion type sintered sliding material having sufficient  strength and excellent sliding characteristics, by specifying the composition of the base material  for the sintered sliding material and further by enlarging the particle size of free graphite coarse  particles.  
     CONSTITUTION: The base material is one compound of ferrite, ferrite plus pearlite or pearlite  which comprises 0.05W1.0wt% P, 0.3W12wt% at least one element of Mn, Ni, Cu and Sn and  the remainder of Fe and inevitable impurities. 1W15wt% free graphite coarse particles having a  particle size of 100W32 mesh are dispersed in the base material. At first, an intermetallic compound between P and the above-mentioned Mn, etc. is prepared and then the powder of the compound together with the natural graphite powder having the above-mentioned particle size is  mixed with powdered iron raw material. The mixture is molded into a green compact and then is  sintered. In this process, the above-mentioned intermetallic compound forms a liquid phase, diffusing rapidly into the inside of iron particles. In particular, P diffuses readily, enhancing bonding  strength between iron particles and the base material is markedly strengthened by the effect of  solid solution. Further, the above-mentioned structure can be obtained by the selection of a proper  sintering condition. Further because the graphite is not covered by the plastic flow of the base material, the sliding characteristics of the sliding material can be ensured.
