摘要： A composite member includes: a substrate formed of a composite material containing a plurality of diamond grains and a metal phase; and a coating layer made of metal. The surface of the substrate includes a surface of the metal phase, and a protrusion formed of a part of at least one diamond grain of the diamond grains and protruding from the surface of the metal phase. In a plan view, the coating layer includes a metal coating portion, and a grain coating portion. A ratio of a thickness of the grain coating portion to a thickness of the metal coating portion is equal to or less than 0.80. The coating layer has a surface roughness as an arithmetic mean roughness Ra of less than 2.0 μm.

摘要： A composite member excellent in corrosion resistance of a substrate and excellent in heat radiation property is provided. A composite member includes a substrate composed of a composite material containing magnesium or a magnesium alloy and SiC and a coating layer provided on a surface of the substrate. The coating layer includes an outermost layer provided as an outermost surface and an intermediate layer provided directly under the outermost layer. The outermost layer contains nickel and phosphorus. The intermediate layer is mainly composed of copper. The intermediate layer has a thickness not smaller than 30 μm.
