Fretting Corrosion in Airframe Riveted and Pinned Connections

Abstract

This year, URI-Initiation project examined the fretting and corrosion response of multiple rivet, one and two rivet-row, lap joints. Tribological parameters governing fretting as well as the effects of intereference and clamping on fretting wear and fretting fatigue have been evaluated using 2-D and 3-D finite element analyses. A piezoelectrically-driven fretting wear machine that can simulate the fretting conditions in connections has been constructed. In this way the specific fretting wear rates of 7075-T6 and 2024-T3 in contact with aluminum and hardened steel under dry and corrosive conditions have been measured. Finally, small, one-rivet-row and 2-rivet-row lap joints have been cyclically tested under dry and corrosive conditions and examined for fretting damage.
