    摘要: A composite metal material for a friction brake composed of a sliding friction surface metal layer of grey cast iron and a layer of a high strength different metal having a crack transmission resistance. The grey cast iron and high strength different metal are metallurgically bonded together. In this composition metal material, cracks formed in the sliding friction surface metal layer are prevented from spreading by the high strength different metal having a high crack transmission resistance. An intermediate metal layer may be provided if desired.
