Abstract
Methods for fabricating a friction bearing, in particular for ceramic shafts, made of metallic hardenable sintered material having an open pore volume of at least 15%, wherein the sintered material is brought into a predetermined shape and is subsequently sintered. For improving the known friction bearings in that a local wear and tear of shaft and bearing is avoided or at least considerably reduced in the region of mixed friction with high lateral forces, it is provided to harden the friction bearing after the sintering.
