Abstract:

PCT No. PCT/EP88/00263 Sec. 371 Date Oct. 6, 1989 Sec. 102(e) Date Oct. 6, 1989 PCT Filed Mar. 30, 1988 PCT Pub. No. WO88/07913 PCT Pub. Date Oct. 20, 1988.A ceramic sealing component for a machine whch is in frictional contact and has at least one non-reflective sliding and sealing face of a mean roughness (Ra) greater than 0.1 and a minimum of 0.8 mu m is described. A component of this type can be produced by subjecting a green ceramic article to shaping, sintering, processing by face-grinding or round-grounding, optionally washing and then abrasive-polishing in the presence of an aqueous phase until the mean roughness desired for the machine component is reached.
