SLIDE MEMBER AND SLIDE MEMBER OF INTERNAL COMBUSTION ENGINE

To provide a slide member having an excellent abrasion resistance and a slide member of an internal combustion engine.SOLUTION: A slide member includes a base material and a coating layer formed on a slide part on the base material. The coating layer has a steel part derived from multiple austenite stainless steel particles, a copper part derived from multiple copper particles or copper alloy particles, and a hard particle part derived from multiple hard particles harder than the steel part. The steel part and the copper part are bonded through an intermetallic layer comprising a component element of the steel part and a component element of the copper part at a boundary, and the base material and the steel part and/or the base material and the copper part are bonded through the intermetallic compound at the boundary. The hard particle is comprised of at least one type of hard particle selected from a group consisting of an iron based alloy particle, a cobalt based alloy particle, a chromium based alloy particle, a nickel based alloy particle and a molybdenum based alloy particle.SELECTED DRAWING: Figure 7 【課題】優れた耐摩耗性を有する摺動部材及び内燃機関の摺動部材を提供する。【解決手段】摺動部材は、基材と、基材上の摺動部位に形成された被膜層と、を備え、被膜層が、複数のオーステナイト系ステンレス鋼粒子に由来の鋼部と、複数の銅粒子又は銅合金粒子に由来の銅部と、鋼部よりも硬質である複数の硬質粒子に由来の硬質粒子部とを有し、鋼部と銅部とが界面において鋼部の成分元素と銅部の成分元素とを含む金属間化合物層を介して結合しており、基材と鋼部と、及び／又は基材と銅部とが界面において金属間化合物層を介して結合しており、硬質粒子が鉄基合金粒子、コバルト基合金粒子、クロム基合金粒子、ニッケル基合金粒子及びモリブデン基合金粒子からなる群より選ばれた少なくとも１種の硬質粒子からなる。【選択図】図７
