“…In addition, wear debris 'rolls' were observed on the worn surface, which are associated with tribochemical wear [39][40][41]. Nevertheless, it is probable that the wear rate associated with this mechanism was far smaller than for the microabrasion.…”

“…[16][17][18] The dominant wear mechanisms in the two regimes are different. For SiCbased materials, mild wear usually occurs by ploughing (or microabrasion) and tribochemical reactions between the sliding surface and water vapor in the air, and severe wear occurs by microfracture.…”

Silicon carbide (SiC) ceramics have good wear resistance but poor friction properties under dry sliding conditions. To lower the friction of SiC, a novel porous carbon material called rice bran carbon (RBC) was added into SiC to make SiC/RBC composite ceramics. The SiC/RBC composites were prepared by mixing one of three kinds of RBC powders having different particle sizes and a fine SiC doped with Al 4 C 3 and B 4 C additives and sintering at 1600°C for 5 min by a pulse electric current sintering (PECS) method. The mechanical and tribological properties of the SiC/RBC composites were evaluated and compared with those of monolithic SiC, monolithic RBC bulk material, and SiC/graphite composite. The SiC/RBC composites not only had superior fracture strength (3-4 times as high as that of the monolithic RBC material) but also showed low friction coefficients (around 0.25) and high wear resistance (at a level of 10 −6 mm 3 N −1 m −1 ) when slid against a silicon carbide ceramic counterface during block-on-ring sliding tests under dry conditions. Compared with the conventional SiC/graphite composite, the SiC/RBC composites had higher mechanical strength, lower friction coefficients, and better wear resistance.

“…There have been several studies investigating the tribological behaviour of SiC and alumina mated against steels [7][8][9][10][11] or self-mated [12][13][14][15][16][17]. However, the influence of possible tribochemical reactions when ceramics are mated against different steels has not been in focus of former research.…”

There have been several studies regarding the tribological behaviour of ceramics such as SiC and alumina mated against steels or self-mated. Nevertheless, only little is known about possible tribochemical reactions when ceramics are mated against steels. In the present study, ceramic pins made of SiC (EKasicF) or alumina (F99.7) respectively were tested under dry sliding conditions against different steel disc counter bodies using a pin-ondisc tribometer. The different ceramics showed significant differences in their tribological behaviour, i.e., coefficient of friction and wear amount. Especially, the SiC couples showed significant differences in the wear amounts while these were quite similar for the alumina couples. The wear behaviour of the SiC couples is discussed in more detail. A correlation between chromium content of the steel discs was found for the SiC couples. The surfaces of selected specimens were analysed by Auger-Electron-Spectroscopy (AES). Wear for the SiC couples was mainly attributed to tribochemical reactions as far as the steel disc was containing the alloying element chromium in considerable amount. Furthermore, a simple wear schematic is proposed.
