Abstract

A test rig was developed for high-frequency fretting conditions (20 kHz, 4.5-24 μm amplitudes) with superimposed macroscopic sliding (1 Hz, 1-10 mm stroke length). Using this tribometer, the high-frequency frictional behaviour and wear characteristics of PTFE, PTFE + 10% carbon fibres, PI, PI + 30% PTFE, PI + 20% carbon fibres and PI + 20% carbon fibres + 20% PTFE on 100Cr6 were studied with respect to their application as contact materials in travelling wave piezoelectric ultrasonic motors. The experimental results obtained for alumina on alumina, which is frequently used in micropush motors, are also discussed.
