✦ Synopsis

The present investigation studies the effect of physiological solution at 37 Β°C on the cyclic deformation behaviour of a Ti-6AI 4V alloy, with a microstructure corresponding to that obtained in the substrate when a sintered metallic porous coating is produced. Cyclic deformation tests have been carried out up to fracture and the fatigue crack nucleation mechanisms have been analysed. Since fatigue is a phenomenon related with plastic deformation, which is enhanced at corrosion and/or at stress concentration sites, cyclic deformation tests conducted at a level of stress above the elastic limit can provide a clear picture of the crack nucleation mechanisms involved.

## Abstract Stem modularity in total hip replacement introduces an additional taper joint between Ti‐6Al‐4V stem components with the potential for fretting corrosion processes. One possible way to reduce the susceptibility of the Ti‐6Al‐4V/Ti‐6Al‐4V interface to fretting is the surface modification
