摘要： A laminate includes a base substrate, and a coating layer formed on the base substrate. The coating layer includes a copper alloy portions derived from precipitation-hardening copper alloy particles and hard particle portions which are harder than the copper alloy portions, the hard particle portions are derived from hard particles, and the parts bond with each other via an interface. Each of the hard particle portions has a non-spherical shape.
A sliding member includes the laminate in at least one sliding portion.
A method for manufacturing a laminate includes a step of spraying a mixture in a non-molten state including precipitation-hardening copper alloy particles and hard particles having a non-spherical shape and being harder than the copper alloy particles onto a base substrate, to form a coating layer on the base substrate.-

摘要： A sliding member includes a base substrate and a coating layer formed on the base substrate. The coating layer includes a copper alloy part derived from a plurality of precipitation hardening copper alloy particles. The copper alloy parts are bonded to each other via interfaces between the copper alloy parts. The copper alloy part contains nickel and silicon as additive elements. The copper alloy part contains 2 to 5 percent by mass of nickel.
A sliding member for an internal combustion engine includes the sliding member at a sliding part of the internal combustion engine.-

摘要： A sliding member of the present invention includes a coating on a base material. The coating contains hard metal particles and corrosion-resistant metal particles that have hardness lower than that of the hard metal particles. The hard metal particles contain particles that have at least Vickers hardness of 600 Hv or higher. The corrosion-resistant metal particles are made of at least one kind of metal selected from the group consisting of copper (Cu), cobalt (Co), chromium (Cr), and nickel (Ni), or are made of an alloy containing said metal. The coating has a cross section in which the hard metal particles are dispersed in an island manner in a particle aggregate of the corrosion-resistant metal particles and in which an area ratio of the corrosion-resistant metal particles is 30% or larger. Thus, corrosion of the hard metal particles in the coating is prevented, whereby the sliding member maintains wear resistance for a long time.
