Beschreibung
Zusammenfassung:	This sliding member comprises a substrate, and a coating layer formed on the substrate. The coating layer includes: an inorganic part derived from a plurality of inorganic particles of at least one type selected from the group consisting of iron-based alloy particles, cobalt-based alloy particles, chrome-based alloy particles, nickel-based alloy particles, molybdenum-based alloy particles and ceramic particles; and a metal part derived from a plurality of metal particles of at least one type selected from the group consisting of other iron-based alloy particles, copper particles and copper alloy particles. The parts are bonded via an interface. In the sliding member, the interface between the substrate and coating layer and the interface between the parts each at least partially comprise an interface layer having at least one among a diffusion layer and intermetallic compound layer. The interface layer has a thickness of at most 2µm.
