Summary

INTERFACES BETWEEN METALS AND POLYTETRAFLUORETHYLENE (TFE) ARE COMMON IN CRYOGENIC SYSTEMS. THIS PAPER PRESENTS RESULTS FROM MEASUREMENTS OF THE TEMPERATURE DEPENDENCE OF THE DYNAMIC COEFFICIENT OF FRICTION BETWEEN COMMERCIALLY PURE COPPER AND TFE. THE EFFECT OF THE COPPER SURFACE FINISH WAS ALSO DETERMINED. THE EFFECTS OF LOAD AND SPEED WERE EVALUATED OVER A SMALL RANGE, BUT NEARLY ALL DATA WERE TAKEN AT A SURFACE SPEED OF 54 MM/S WITH A LOAD OF 16.3 KILOPASCAL. THESE VALUES ARE TYPICAL OF THOSE ENCOUNTERED BY THE MOVING PARTS OF SOME CRYOGENIC MACHINERY.
