Abstract
The invention concerns a sliding body for sliding systems in which sliding surfaces of sliding and counter components form a gap in which there is a fluid, whereby the sliding body (1) at least in the area of sliding surfaces (10) is comprised of several stacked thin form elements stamped out of foils or cards, which are solidly bonded together on the contact faces. The invention also concerns a process for the production of the sliding body, whereby foils are produced from ceramic slips, in which various hollow chambers and/or recesses are stamped or impressed, a laminating agent is applied to the foils or cards, the foils or cards are stacked into a sliding body packet and the layers of the stack are laminated together, the organic components are partially baked off, after which a post-treatment of the sliding body takes place, then the remainder of the organic components are removed, and then the laminated sliding body is sintered between 1200.degree. and 2200.degree. C., after which an optional post-treatment takes place. The novel sliding body is used especially for production of hydrodynamic enhancement shapes in the sliding surface.
