Abstract

The invention relates to a component that is suitable for use as a sliding bearing. The invention further relates to a method for the production of said component. The design of the component according to the invention provides a layer of a light metal material (13), which is provided with an oxide layer (15) containing pores (16) in the direction of the sliding surface (23) of the component. A hard material (18) is placed in the pores, which greatly increases the firmness of said layer region, thus creating the mechanical firmness for use as a sliding bearing. In order to counteract the tendency of said firm layer region to experience brittle failure, the oxide layer (15) is coated with a solid lubricant layer (20). Said solid lubricant layer comprises a metallic, ductile matrix (21), which distributes a force (F) acting at certain points over a larger surface region (b). In order to improve the sliding characteristics, particles of a solid lubricant (22) are simultaneously embedded in the solid lubricant layer (20).
