Popis:	The fretting corrosion of a Ti–6Al–4V flat in contact with a poly(methyl methacrylate) (PMMA) ball in 0·9 wt-% NaCl solution was investigated using a fretting rig operating under electrochemical control. The effect of potential and of normal load on friction, wear and electrochemical response was studied under gross slip regime. No noticeable mechanical deterioration of the Ti–6Al–4V surface could be observed. At anodic potential, alloy corrosion was only slightly enhanced by fretting. Wear of PMMA was large and controlled by third body formation. A correlation between PMMA wear coefficient and thickness of third body was observed.
