Title: PLAIN BEARING COMPOSITE MATERIAL HAVING A METALLIC SUPPORT LAYER AND A METALLIC BEARING METAL LAYER
Abstract:
The invention relates to a plain bearing composite material (2) having a metallic support layer (4) and a metallic bearing metal layer (6), wherein the bearing metal layer (6) is a sinter layer (10) made of a copper/tin-based bronze powder (8), wherein the bronze powder (8) comprises a metallic solid lubricant (12) which is not soluble or barely soluble in copper, such as in particular bismuth, and is applied to the support layer (4) in a pulverulent state and then sintered onto the support layer (4); according to the invention it is proposed that the bronze powder (8) is formed from powder fractions having different proportions of this solid lubricant (12), wherein the solid lubricant proportion of a first powder fraction is greater than the solid lubricant proportion of a second powder fraction at least by a factor of 2.
