Abstract

Friction, wear, and resistivity are reported for monolithic glassy carbon and a composite made of copper fibers in a glassy carbon matrix. Reduction of atmospheric oxygen is shown to reduce the wear rate for both of the materials, thereby indicating that the contact behavior is different from that of graphite. Repeats of earlier measurements of tribological behavior of glassy carbon on glassy carbon confirm the low wear rate reported previously and show marked lowering of the friction coefficient in a long run (724 km or sliding)
