摘要

The problem of good wear resistance coupled with low friction coefficient has been studied extensively. Carbide-derived carbon (CDC) films have been demonstrated to show excellent friction and wear properties in air. In the present work, we examine the effect of humidity on the tribological behavior of CDC films prepared under various experimental conditions. We produced the films by high temperature chlorination of sintered silicon carbide, characterized them by Raman microspectroscopy and nanoindentation, and carried out pin-on-disk tribological tests in air and dry nitrogen (0% humidity) using silicon nitride counterbodies. Our results indicate that CDC, unlike graphite or glassy carbon, does not fail in dry environments. Moreover, it performs better in dry nitrogen than in humid laboratory air. The CDC coating on SiC can work for hours in dry nitrogen showing the friction coefficient of less than 0.05. Chlorination conditions and the surface condition of the test piece are other important parameters in tribological performance. These coatings may be used in dynamic seals and other tribological applications.
