Abstract: [Task] The adhesion resistance of Cu—Bi based or Cu—Sn—Bi based alloy is lower than that of Cu—Sn—Pb based alloy, and also since conformability of the former alloy is low. Therefore, when Bi of the former alloy adheres onto an opposite shaft, seizure of the former alloy is likely to occur as compared with the case of the latter Cu—Sn—Pb based alloy. In is alloyed in the Bi phase of the Cu—Sn—Bi—In based copper alloy. The In-alloyed Bi phase has a considerably low melting point and therefore the sliding properties deteriorate.[Means for Solving] A Pb-free copper-based sintered sliding material has a composition that 0.5 to 15.0 mass % Bi and 0.3 to 15.0 mass % In, with the balance being Cu and inevitable impurities. With regard to the existence of Cu, Bi, and In, the material consists of a Cu matrix containing In, a Bi phase, and an In concentrated region in said Cu matrix at a boundary of said Bi phase.

Abstract translation: [任务] Cu-Bi系或Cu-Sn-Bi系合金的耐附着性比Cu-Sn-Pb系合金低，并且由于前者合金的贴合性低。 因此，当前一种合金的Bi附着在相反的轴上时，与后一种Cu-Sn-Pb基合金的情况相比，容易发生前者合金的咬合。 In在Cu-Sn-Bi-In系铜合金的Bi相中合金化。 合金化双相具有相当低的熔点，因此滑动性劣化。 [解决方法]无铅铜系烧结滑动材料具有0.5〜15.0质量％Bi和0.3〜15.0质量％In的组成，余量为Cu和不可避免的杂质。 关于Cu，Bi和In的存在，该材料由在所述Bi相的边界处的所述Cu基体中含有In，Bi相和In浓缩区域的Cu基体组成。
