Abstract:Using a ball-on-flat contact mode, the torsional fretting wear of 5083 aluminum alloy flats against GCr15 steel ball were investigated under normal load(15, 50N) and torsional angular displacement amplitudes(from 0.1°to 10°).The results reveal that the T-θcurves change with the increasing of cycle numbers. It shows three types, i.e. the linear, elliptic and parallelogram loops.The torsional fretting running behaviors of 5083 aluminum alloy can be defined as three fretting regimes(i.e. partial slip regime(PSR), mixed fretting regime(MFR) and slip regime(SR)).The friction torque has a low value in the PSR but changes regularly in the MFR and SR. The wear scars observed by SEM reveal that the damage in the PSR is slight but serious damage wear is observed in the MFR and SR. The running condition fretting maps of 5083 aluminum alloy are set.
