Abstract

This paper examines the evidence for a plasticity based wear mechanism in the fretting wear of Ti-6Al-4V. Driven by near-surface plastic strain accumulation, the generation of wear debris evolves from coarse metallic debris towards loose fine oxide debris generating W-shape wear scar. The overall wear effect however, is less pronounced at the later stages of wear due to a reduced propensity for plastic deformation in the contact associated with reductions in the contact pressure due to wear in the contact. The evidence suggests that the high wear rate at the early stages of a fretting test are due to debris generation associated with gross plasticity whilst at the later stages, lower wear is associated with less plasticity accumulation.
