Samples of 100Cr6-bearing steel were treated by different ion beams in
order to study the evolution of their tribological properties.
Complementary physico-chemical characterisation techniques give
evidence for a strong correlation between the amount of surface carbon,
whatever its origin (contamination, direct C implantation or ion beam
mixing of a deposited carbon layer), and the reduction of the friction
coefficient as well as the increase of the wear resistance. It is found that
the friction coefficient is improved by a factor 5 and the wear volume
by two orders of magnitude when the amount of surface carbon exceeds
.
