Research on Ultra Low Wear Materials for Energy Conservation: Final Report.

摘要

This report summarizes a set of friction and wear measurements for glassy carbon based materials run against a broad range of counterfaces in ball on disk wear machines. The carbon based materials were operated as both riders and disks. The principal runs employed 1 N contact load, and special runs for the carbon on its own kind extended the load to 20 N. Runs were carried out in laboratory air and in dry nitrogen and argon. Wear was measured on the rider, alone. The general trend of the results showed favorably low wear coefficient for the carbon based materials. They showed much less sensitivity of the wear rate to the replacement of the air by dry nitrogen than would have been experienced by graphitic carbon.
