摘要： PROBLEM TO BE SOLVED: To provide a current-collecting sliding material having improved abrasion resistance and lubricity, and to provide a method for producing the same.SOLUTION: A current-collecting sliding material is composed of a sintered alloy obtained by sintering a raw material powder, the raw material powder containing: (1) sulfur free-cutting iron powder containing 0.5-2.5 mass% of MnS; (2) Cr-based hard particles including Cr particles and CrV particles; (3) Fe-based hard particles including FeMo particles and nitrided FeTi particles; and (4) a metal sulfide containing MoSand WS. (1) The sintered alloy contains Cr: 4.0-14.0 mass%; V: 0.2-3.0 mass%; Mo: 2.0-6.5 mass%; Ti: 0.2-3.0 mass%; W: 0.2-3.0 mass%; Mn: 0.1-1.1 mass%; S: 1.0-5.0 mass%; and N: 0.05-0.4 mass%, with the balance being unavoidable impurities and Fe. (2) The sintered alloy contains, in terms of area ratio, 2.0-17.0% of the Cr-based hard particles and 1.0-15.0% of the Fe-based hard particles in a texture cross section thereof, and also contains 1.0-5.0 mass% of the metal sulfide including MoSand WS.
