ABSTRACT:
Internal combustion engine with bearing shells, which are formed essentially by thermal sprayed bearing layers, wherein the thermal sprayed bearing layers are formed by at least two slide bearing materials with different hardness, which are spatially separated from each other and are provided on the outer surface of the bearing shell, as well as process for production of bearing shells for internal combustion engines including the steps:mechanical conditioning of the bearing surfacecoating of the bearing surface with the materials of the bearing shell by thermal spray processesfinishing flattening processing of the applied layerwherein as bearing shell at least two slide bearing materials with different hardness were deposited separated spatially from each other, wherein the materials are in contact with each other via interlayers or joint layers.
