“…We observed no drawn particles on the surface of the oriented UHMWPE. As noted in our previous work, some waves or ripples oriented perpendicular to the sliding direction were present on the surface of the materials (Figs (a) and (c)). At a higher magnification than the one used to record the micrographs of the present paper (micrographs not shown here), we measured the average wave thickness which was approximately 2 µm for the non‐oriented material and 1 µm for the oriented material, confirming our previous results for 50 000 cycles …”

“…In a previous study, the sliding dissipated energy was supposed to be proportional to wear volume, but this hypothesis was not verified. In particular, dry reciprocating sliding tests were done on oriented UHMWPE with a residual strain of 0.85 up to 50 000 cycles and it was found that the wear was not important enough to be accurately quantified.…”

“…These authors did not find any significant difference between the wear resistance of oriented UHMWPE and that of non‐oriented UHMWPE. In our previous paper, the impact of a tensile‐induced orientation on the reciprocating sliding behaviour of UHMWPE under dry testing conditions was investigated. After 50 000 sliding cycles, the cumulative sliding dissipated energy decreased by 40% and 60% when comparing untreated UHMWPE with oriented UHMWPE (true axial strain ϵ 33 = ln( l / l 0 ) = 1.15 corresponding to a nominal strain ϵ n of 216%) for sliding tests performed parallel and perpendicular respectively to the chain direction.…”

The impact of processing-induced chain orientation on the sliding wear behaviour of ultrahigh molecular weight polyethylene (UHMWPE) was investigated. The orientation of the molecular network of UHMWPE was done by means of uniaxial tension up to different residual strains. We found that high residual strain levels (higher than 0.45) enabled the sliding dissipated energy of UHMWPE to be decreased in dry conditions. In particular, oriented UHMWPE with a residual strain of 0.85 exhibited, at 500 000 sliding cycles in dry conditions, a decrease in volumetric wear loss by a factor of 3.3 and 19.4 compared with the reference UHMWPE tested in directions parallel and perpendicular to the chain direction, respectively. It is argued that oriented UHMWPE exhibits less adhesion during interfacial wear than the reference material, and hence orientation of UHMWPE bulk may be an alternative treatment to crosslinking for dry sliding conditions. In the case of sliding testing conducted in Ringer's solution, the benefit of the initial chain orientation was quite weak due to a lubrication effect of the solution that markedly limited the effect of chain orientation on the sliding behaviour.

“…In other words, tribological events are affected by corrosive mechanisms, and likewise, there may be significant variation in the corrosion process under the tribological exposure. It has already been reported that the total degradation loss is not a simple summation of wear loss or corrosion loss, but much more multifactorial [12][13][14]. This indicates the need to clearly distinguish the pathways of the degradation mechanisms.…”

Metal/alloys have been used in orthopedic and dental implants for many years. In a physiological environment, they are susceptible to materials degradation affecting its performance and lead to gradual and early failures due to the continuous exposure to the variation in in vivo mechanical and chemical conditions. Tribocorrosion is a new area of research that links tribology and corrosion, which can be defined as the irreversible material degradation process resulting from the synergistic interaction of wear and corrosion phenomena on surfaces subjected to a relative contact movement in biological environments. This book chapter describes some fundamental aspects about this new research area and focused on its significances in biomedical application, namely, orthopedics and dentistry.

“…Thermal models have been developed to study interface effects at contacting surfaces (Majcherczak, Dufrenoy et al 2007). Frictional energy can be dissipated through different mechanisms such as oxidation, rise in temperature, formation of wear particles, entropy changes associated to viscoelastic and viscoplastic deformation, and noise generation (Eddoumy, Addiego et al 2011). Studies of friction brake show that more than 95% of the dissipated energy is transformed into heat (Kasem, Thevenet et al;Majcherczak, Dufrenoy et al 2007).…”

Abstract. Brake pad materials for automobile applications are basically polymer matrix composites. Various reinforcing constituents used in brake pads are organic, metallic and ceramic fillers which play among others an important role on the mechanical and thermal properties, and the wear resistance at high temperature. Friction and wear depend on various parameters such as the micro-chemical structure of the pad and of the metallic counter-face, the rotation speed, the pressure, and the contact surface temperature (M.G. Jacko 1983). This latter parameter can be locally as high as 600 up to 1.500• C depending on the brake type (M.G. Jacko 1983; Blau 2001). Thermal models have been developed to study interface effects at contacting surfaces (Majcherczak, Dufrenoy et al. 2007). Frictional energy can be dissipated through different mechanisms such as oxidation, rise in temperature, formation of wear particles, entropy changes associated to viscoelastic and viscoplastic deformation, and noise generation (Eddoumy, Addiego et al. 2011). Studies of friction brake show that more than 95% of the dissipated energy is transformed into heat (Kasem, Thevenet et al.;Majcherczak, Dufrenoy et al. 2007). Thermal analysis is therefore a primordial step in the study of brake systems since it provides thermo-mechanical properties (Majcherczak, Dufrenoy et al. 2007). The influence of the addition of metallic fibers on the performance of organic friction composites has been investigated using friction tests (Qu, Zhang et al. 2004). Benefits or limitations of the different fibers have been reported, however the issues of thermomechanical properties or effect of temperature on friction and wear behavior were not yet investigated (Bijwe, Kumar et al. 2008). No effort was done to correlate the thermo-mechanical and thermal properties with the friction and wear behavior. An important prerequisite is to get a good understanding on how brake materials behave. However, a link between thermal transitions and tribological behavior occurring at different temperatures is still missing.This investigation is focused on the effect of thermal properties of brass-free and brass containing brake pad composites on their friction and wear behavior to analyze the benefit of brass addition. Hereto, the impact of the incorporation of brass into the composites on their degradation was determined from TGA measurements. In a second step, heat transfer and thermal diffusivity were determined with hot disk to study the effect of brass on the thermal transport properties of brake pad composites. Friction and wear behavior were investigated under reciprocating sliding performed at room temperature (RT) up to 400• C. The coefficient of friction and the dissipated energy were analyzed for both brass-free and brass containing composites. The observation of the wear track enabled us to suggest a possible relationship between the thermal and mechanical properties on one side, and the friction and wear behavior on the other side.TGA results indicate that thermal decomp...
