1. A sliding member comprising:
a steel back metal layer; and a sliding layer on the steel back metal layer, the sliding layer including a porous sintered layer and a resin composition, wherein the porous sintered layer includes a Ni—P alloy part and Fe or Fe alloy granules, wherein the Ni—P alloy part functions as a binder for binding the Fe or Fe alloy granules with one another and/or for binding the Fe or Fe alloy granules with the steel back metal layer, and wherein the steel back metal layer is made of a carbon steel including 0.05 to 0.3 mass % of carbon, and comprises:
a non-austenite-containing portion in a central portion of a thickness direction of the steel back metal layer, the non-austenite-containing portion having a structure of a ferrite phase and perlite formed; andan austenite-containing portion in a surface portion of the steel back metal layer facing the sliding layer, the austenite-containing portion having a structure of a ferrite phase, perlite and an austenite phase. |
