ABSTRACT:
In a composite material manufactured by connecting a sintered body to a surface of a metal substrate, the connection strength under a high temperature is increased, stress relaxation in the composite material is attained, and the strength, wear resistance and corrosion resistance are improved. The sintered body has a multilayer structure having layers with different compositions, i.e. compositions that vary or differ in a direction perpendicular to the connection surface, and the volume relation between the respective layers of the sintered body and the substrate is (substrate volume.times.0.2).gtoreq.(sintered body volume
umber of layers), while the thickness of each layer is at least 0.2 mm and not more than 5 mm.
