Embodiment Construction
[0078] At least one type of powder selected from the group consisting of the iron powder, the alloy iron powder and the alloy elements powder was blended and kneaded with powder of the hard particles (and optionally with the solid lubricant powder) as shown in Table 1, whereby the mixed powder was obtained. The blended amount of each component powder was indicated as wt % with respect to the total amount of the mixed powder.
[0079] The types of the alloy iron powder which was used are: (A) alloy steel powder containing 1.0% of Cr, 0.5% of Mn, 0.3% of Mo and Fe as the remainder; (B) alloy steel powder containing 3.0% of Cr, 0.2% of Mo and Fe as the remainder; (C) alloy steel powder containing 4.0% of Ni, 1.5% of Cu, 0.5% of Mo and Fe as the remainder. Here, "%" represents "wt %".
[0080] The types of the hard particles which were used are: (a) powder of carbide-precipitated particles (the average particle diameter being 80 .mu.m, the average particle diameter of carbide being 3 .mu.m) o...
