摘要： A bearing material consists of a matrix of a metal alloy forming a monotectic system with Pb-based materials and substantially bead-shaped soft phases of a Pb-based material dispersed therein in such a way that the concentration of the soft phases increases in the matrix towards a surface of the bearing material. It is made by casting a melt containing in the mixture alloying components which form a monotectic system with Pb-based materials and alloying components which form a Pb-based material on a substrate in such a way and thus by setting the material thickness, the cooling conditions and the composition of the melt in such a way that the Pb-based material separates in the liquid state from the rest of the melt under the force of gravity and is concentrated in dispersed fashion in the lower region of the material.
