<p>PCT No. PCT/FR92/00258 Sec. 371 Date Oct. 25, 1993 Sec. 102(e) Date Oct. 25, 1993 PCT Filed Mar. 20, 1992 PCT Pub. No. WO92/16473 PCT Pub. Date Oct. 1, 1992.Process for the preparation of ceramic materials for parts having friction surfaces subject to friction and free from auto/self-adhesion under stress or during aging. A precursor of the ceramic undergoes successive operations of pressing, sintering, polishing the surface obtained, cleaning the solid gangue resulting from the polishing, roasting in the presence of oxygen, and a treatment aimed at increasing the dielectric susceptibility and homogeneity of the ceramic material adjacent the friction surfaces and to increase the mobility of charges.</p> |
