Abstract
Measurements under potentiostatic control have been made of the increase in corrosion current when fretting occurs on the surface of various copper and aluminium alloys. Polarisation measurements on copper alloys indicate that the increase in corrosion current density due to fretting can be of the order of 1500 times. The increase in corrosion is attributed to continual rupture of oxide films and, to a lesser extent, to plastic deformation in the contact region.
