Abstract:
The aim of this work was to study the damage caused by fretting-corrosion of the press fit used to maintain the femoral head on the stem of modular hip prothesis. In the case of metallic compounds, the femoral head and stem can be made with 316L and Ti-6Al-4V. Their contact was studied in a cylinder/plan configuration. The first experiments were realized in air under gross slip condition in order to show the mechanical loading effect on the practical damage. Thanks to the results obtained from tests performed in the Ringer's solution (used as physiological medium), a phenomenological model based on short distances interactions was proposed to explain the modification of the fretting regime observed. The second part of the study consists in the contact optimisation by the way of the use of the 316LN and the realisation of surface treatments on both materials. A quantitative analysis of wear is conducted in order rank the wear resistance of the different materials.
