Ceramic particulate composites in the system SiC–TiC–TiB 2 sliding against SiC and Al 2O 3 under water

The tribological behaviour of SiC, SiC–TiC and SiC–TiC–TiB 2 was determined in oscillating sliding against SiC and α-Al 2O 3 in water at room temperature. The tribo-systems with the composite materials containing TiC and TiB 2 differ significantly from the systems with the single phase SiC: The wear...

Summary:The tribological behaviour of SiC, SiC–TiC and SiC–TiC–TiB 2 was determined in oscillating sliding against SiC and α-Al 2O 3 in water at room temperature. The tribo-systems with the composite materials containing TiC and TiB 2 differ significantly from the systems with the single phase SiC: The wear is reduced and the friction is increased. The wear reduction up to a factor of 10 is mainly due to the formation of an oxide film containing titanium oxides which is soft, stable in water and well adhering to the bulk material. This oxide film is transferred to the alumina ball but not to the silicon carbide ball.
