Abstract
A method of producing a composite material, in particular for sintered slide bearings and slide bearings. Composite materials for sintered slide bearings consist of at least one ceramic sintered material and at least one metallic sintered material and have a short service life during operation at low speeds of the shaft and in the case of a simultaneously high radial load because the lubricant stored in the bearing cracks. The novel sintered bearing is to have a long service life under such operating conditions. In the novel bearing use is made of ceramic sintered materials which have a high thermal conductivity, e.g. boron nitride. The novel composite material and the novel slide bearing are particularly suited for electric miniature motors comprising a ceramic shaft.
