Abstract
The invention provides a hard-particle powder for sintered body, which contains, by mass %, 2% to 3.5% of Si, 6% to 10% of Cr, 20% to 35% of Mo, 0.01% to 0.5% of REM, and the remainder being Co and unavoidable impurities. The invention further provides a sintered body obtained through a mixing step of mixing the above-mentioned hard-particle powder for sintered body with a pure iron powder and a graphite powder to obtain a powder mixture, a forming step of compacting the powder mixture to obtain a compact, and a sintering step of sintering the compact. The hard-particle powder according to the invention has the effect of giving a sintered body having improved wear resistance without substantially impairing powder characteristics and sintering characteristics. Additionally, the sintered body according to the invention has the effect of having excellent wear resistance.
