the electrical and tribological properties of metal fibre sliding contacts are studied. the cu-cd fibres have a diameter of 50 $mu$ m. they slide on cu-cr tracks with optional surface treatments (gold electroplated on a nickel underplate). the working atmosphere is generally wet pure nitrogen. several types of experimental results are reported. a microcomputer-controlled test bench is described. results obtained with this set-up show that the temperature and the polarity of the electric field at the brush-track interface have an influence on the mechanisms and speed of wear. the authors present a model adapted from n. cabrera and n. f. mott's copper oxidation theory. the parts played by temperature and by the electrochemical electric field are described. results obtained with the model are presented and are in very good agreement with the experimental results.
