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 (), which is provided with an oxide layer () containing pores () in the direction of the sliding surface () of the component. A hard material () 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 () is coated with a solid lubricant layer (). Said solid lubricant layer comprises a metallic, ductile matrix (), 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 () are simultaneously embedded in the solid lubricant layer ().
