Sintered sliding member and production method thereof |
摘要 |
A sintered sliding member having not only excellent in wear resistance but also low in attacking property against a mated member. To obtain the member, 0.1 to 3.5 wt. % h-BN and 0.1 to 3.5 wt. % graphite are mixed in a matrix material of iron-based powder containing chromium, and a resultant powder mixture is compacted to form a compact. The compact is sintered while bringing the compact into contact with copper or copper alloy so that the copper or copper alloy is infiltrated simultaneously with the sintering. In this way, the copper phase is filled in the iron-based matrix and the h-BN is distributed in the copper phase. Graphite reacts with chromium to be precipitated as chromium carbide in and/or near boundaries defined between the matrix and the copper phase.
