AMORPHOUS CARBON COATING FOR REDUCTION OF FRICTION AND WEAR IN A SLIDE COMPONENT

According to the present invention a non-hydrogenated amorphous carbon coating such as an a-C and/or ta-C coating on a surface of a sliding part is disclosed, wherein the sliding part is foreseen for use under lubricated conditions and occasionally under dry running conditions. The coating is applie...

Beschreibung
Zusammenfassung:	According to the present invention a non-hydrogenated amorphous carbon coating such as an a-C and/or ta-C coating on a surface of a sliding part is disclosed, wherein the sliding part is foreseen for use under lubricated conditions and occasionally under dry running conditions. The coating is applied on a ceramic surface, such as for example surfaces comprising silicon carbide (SiC), carbon containing silicon carbide (SiC-C); silicon embedded silicon carbide (Si-SiC), tungsten carbides (WC), and combinations of previously mentioned materials. La présente invention concerne un revêtement de carbone amorphe non hydrogéné tel qu'un revêtement d' a-C et/ou de ta-C sur une surface d'une partie coulissante, la partie coulissante étant prévue pour une utilisation dans des conditions lubrifiées et occasionnellement dans des conditions de fonctionnement à sec. Le revêtement est appliqué sur une surface céramique, telle que, par exemple, des surfaces comprenant du carbure de silicium (SiC), du carbure de silicium contenant du carbone (SiC-C) ; du silicium incorporé dans du carbure de silicium (Si-SiC), des carbures de tungstène (WC), et des combinaisons des matières précédemment mentionnées.
