For some applications of slide layers, for example in connecting rod bearings of internal combustion engines, for individual sites of a formed piece, high load bearing capability are required while for other places of the same formed piece good embedding abilities are demanded. A composite material with a slide layer applied by cathode sputtering of a tightly cohesive matrix and an insoluble component distributed statistically in it, is adapted to these opposite demands in that the diameter of the particle of the insoluble material has gradients at predetermined sites, which extend parallel to the surface of the slide layer, and to which slide layer hardness gradients correspond. These gradients are generated during the cathode sputtering process in the substrate to be coated to form a growing slide layer having temperature gradients which are maintained and which extend parallel to the substrate surface.

A composite material, comprising at least one cathode sputtering applied slide layer surface of a mixture of particles deposited in a substantially predetermined distribution of at least one cohesive metallic material forming a matrix, and at least one additional metallic material in the solid state

A composite material, comprising at least one cathode sputtering applied slide layer surface of a mixture of particles deposited in a substantially predetermined distribution of at least one cohesive metallic material forming a matrix, and at least one additional metallic material in the solid state, said additional metallic material having particles substantially locked in the matrix material, said locked particles having a diameter which changes at predetermined locations said predetermined locations extending parallel to the surface of the slide layer, said slide layer having a hardness which changes corresponding to the change of the diameter of particles at said predetermined locations thereby providing locations with particles of small mean particle diameter of high hardness and good load bearing ability and locations with particles of larger mean particle diameter with a lower degree of hardness corresponding to good embedding capacity.
