R. Wasche et D. Klaffke, Ceramic particulate composites in the system SiC-TiC-TiB2 sliding against SiC and Al2O3 under water, TRIBOL INT, 32(4), 1999, pp. 197-206
The tribological behaviour of SiC, SiC-TiC and SiC-TiC-TiB2 was determined
in oscillating sliding against SiC and alpha-Al2O3 in water at room tempera
ture. The tribe-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 facto
r 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 materi
al. This oxide film is transferred to the alumina ball but not to the silic
on carbide ball. (C) 1999 Published by Elsevier Science Ltd. All rights res
