摘要

We demonstrate a new concept of self-adaptive materials

where sulphur is incorporated into TiC/a-C coatings and may be released in

for example

a tribological contact. By reactive sputtering with H

sulphur goes into the carbide to form a TiC

phase in an amorphous carbon matrix. The addi

tion of sulphur lowers the friction against steel. Significantly lower friction is obtained against a tungsten counter-surface

as WS

is generated in the contact. Annealing experiments and formation energy calculations confirm that sulphur can be released from TiC

. Ti–C–S coatings are thus chemically active in tribological contacts

creating possibilities of new low-friction systems.
