Pin-on-Disc Tests with Ceramics in Air and Aqueous Media

  • Peter Andersson


The tribological properties of sintered grades of alumina, zirconia-toughened alumina (ZTA), zirconia (PSZ), silicon carbide (SiC) and sialon were studied by means of pin-on-disc tests in air, water and a glycol-based mixture. Without lubrication, the coefficients of friction were slightly to substantially higher than in the aqueous media. During the lubricated tests with SiC and sialon, the sliding surfaces were tribochemicalIy polished and enabled the generation of a fluid film lubrication mechanism with coefficients of friction down to 0.01. With the glycol-based mixture, the wear of PSZ was strongly reduced, while the sliding tracks of the alumina-based ceramics were chemically attacked.
