“…Valero et al, reported that the corrosion rate of CoCrMo is very sensitive to the amount of BSA and thereby it influences the mechanics and kinetics of the corrosion reaction on the material surface [10]. Furthermore, several electrochemical studies have shown that the constituents of bovine serum have an influence on the corrosion behavior of CoCrMo, for example it has shown that the albumin acts as a cathodic inhibitor and it accelerates the anodic reaction in solution [9][10][11][12]. Thus adding BSA to the simulated body fluid (SBF) implies an adequate experimental medium for the corrosion and tribocorrosion test of the present work.…”

“…The damage is restricted mostly to the local movement site, while the generated debris act as abrasive particles. The presence of body fluids represents an additional environmental cause of corrosion at the joint prostheses interface [9]. The natural physiological environment contains not only inorganic species but also organic molecules such as serum proteins.…”

“…Furthermore, mechanically assisted crevice corrosion (as a combination of fretting and crevice corrosion) may attack the alloy and lead to implant failure [7]. Modularity is often associated with corrosion effects and is seen as a weak link with a possible source of complications [24]. A multicentre retrieval analysis of 231 modular hip implants revealed corrosion processes at the modular head-neck connection in more than 28% of the cases [8].…”

Modular neck implants are an attractive treatment tool in total hip replacement. Concerns remain about the mechanical stability and metal ion release caused by the modular connection. Five different implant designs were investigated in an experimental set-up. In vivo conditions were simulated and the long-term titanium release was measured. Finally, the modular connections were inspected for corrosion processes and signs of fretting. No mechanical failure or excessive corrosion could be identified for the implants tested. The titanium releases measured were extremely low compared to in vivo and in vitro studies and were not in a critical range.Résumé Dans les prothèses totales de hanche l'utilisation d'implants avec col modulaire est d'une utilisation fré-quente et pratique. Néanmoins, cette utilisation laisse persister des doutes sur la stabilité mécanique et sur le relargage des ions métalliques. 5 différents implants ont été étudiés en reproduisant les conditions in vivo, en mesurant le relargage de titane et en évaluant la corrosion et les lésions du col. Ce travail n'a pas permis de mettre en évidence d'échec secondaire à une corrosion excessive, et les taux de titane sont restés extrêmement bas dans les limites de l'acceptable.

“…Literature studies showed that the released of metal ions (e.g. Co, Cr, Mo) may interact with the neural system, influence bone mineralization or be carcinogenic [4][5][6][7]. The long term durability of the implants relies on the control of their corrosion resistance and wear behavior.…”

a b s t r a c tNuclear Reaction Analysis -NRA in combination with d-RBS (E d : 1.35 MeV) was applied in order to investigate the corrosion behavior of CoCrMo alloy. The corrosion resistance of the alloy was compared to that of modified CoCrMo samples by several techniques as plasma nitriding and oxidizing at moderate temperature ($400°C). Electrochemical techniques in simulated body fluid 0.9% NaCl (37°C) were applied in order to accelerate the corrosion process. The nitrogen depth distribution before and after the corrosion was determined using the 14 N(d,a) 12 C and the 14 N(d,p) 15 N nuclear reactions whereas the oxygen by the 16 O(d,p) 17 O. The surface morphology and microstructure was investigated using microscopy techniques.It was found that surface treatments produce thick nitrided layers (5-6 lm) consisting of a supersaturated nitrogen solution (nitrogen concentration is $30 at.%) in the matrix (expanded phase c N ) and a thin oxygen solution (0.3 lm). The samples subjected to plasma nitridation and oxidation exhibited the lowest deterioration and better resistance to corrosion compared to the single nitrided or single oxidized and the untreated material. This could be attributed to the modified surface region with the high nitrogen content and the presence of oxygen.
