FIELD: machine building.
SUBSTANCE: invention relates to friction products and can be used in brakes for car and rail vehicles. Product contains steel basis 1 with hollows 2, covered by two layers 3 and 4 of bronze, and cover plate made of ceramic-metal, implemented of two layers 5, 6, corresponding mixture of sintered metallic and non-metallic sintered components. Thickness of layer 4 of bronze considerably increases thickness of bronze layer 3, and layer 5 of ceramic-metal is implemented with cavities, filled by material of layer 6, and amount of silica and graphite oxide in the latter increases amount of those components in layer 5.
EFFECT: adhesion increasing between metallic basis and cover plate, increasing of resistance to formation in cover plate of splits, longitudinal and transverse cracks.
