ABSTRACT:
For producing a component of silicon-infiltrated silicon carbide, having a porous sliding surface, a component of silicon-infiltrated silicon carbide (composition: 40-95% by weight of SiC, 1-45% by weight of carbon particles of grain size 0.1 to 500 .mu.m and 1-25% by weight of silicon) is machined on parts of the surface, a sliding surface thus being produced. The resulting component is heated in an oxygen-containing atmosphere at temperatures from 700.degree. to 1410.degree. C. until the carbon particles present in the sliding surface have been at least partially oxidized with the formation of pores.
