A method to increase the damping of a substrate using a face-centered cubic ferromagnetic damping coating.

Provided is a sliding member having: a back metal layer; and a sliding layer on the back metal layer. The sliding layer includes a porous sintered layer and a resin composition. The sintered layer includes NiP alloy phase and granular steel phase made of a carbon steel including 0.3-1.3 mass % of carbon and having a structure of: ferrite phase; and perlite phase, or perlite phase and cementite phase. The NiP alloy phase binds the steel phases with one another and/or binds the steel phases with the back metal layer. The steel phase includes a low perlite phase part in a surface. The low perlite phase part has an area ratio of the perlite phase lowered by 50% or more compared with a total area ratio of the perlite phase and the cementite phase at a central part of the steel phase when observed in a cross-section.

A thermal spray powder of the present invention contains a rare earth element and a group 2 element, which belongs to group 2 of the periodic table. The thermal spray powder, which contains a rare earth element and a group 2 element, is formed, for example, from a mixture of a rare earth element compound and a group 2 element compound or from a compound or solid solution containing a rare earth element and a group 2 element. The thermal spray powder may further contain a diluent element that is not a rare earth element or a group 2 element and is not oxygen, which is at least one element selected, for example, from titanium, zirconium, hafnium, vanadium, niobium, tantalum, zinc, boron, aluminum, gallium, silicon, molybdenum, tungsten, manganese, germanium, and phosphorus.

A metal conducting structure includes a first metal conducting layer, a second metal conducting layer, and a third metal conducting layer.
