Surface Physics and Chemistry of Electrical Contact Phenomena.

Abstract

The vacuum surface segregation of impurities on copper slip ring materials was studied by Auger electron spectroscopy. In addition the surface chemical composition, electrical contact resistance, and friction were measured in situ for a copper slip ring rotating in vacuum against two copper wire brushes running in separate tracks. The results are embodied in reprints and preprints of 4 papers attached as appendices to the report. (Author)
