Effect of relative humidity on the current-carrying tribological properties of Cu–C sliding contact pairs
TL;DR: In this paper , the authors investigated the variation in the current-carrying tribological properties of Cu-C pairs and the related wear mechanism at different relative humidities, and found that even for an existing tribofilm, the coefficient of friction increased immediately once the humidity support was lost.

Comparative study of the current-carrying tribological properties of carbon graphite composites with different hardnesses
TL;DR: In this article , the effect of sliding speed and electrical current on the current-carrying friction performance of carbon graphite brushes with different hardnesses was investigated, and the results showed that the difference in hardness has a noticeably different effect on the sliding contact resistance and interface temperature rise of the material.
