The corrosion of pure cobalt in physiological media

Cast Co-Cr alloy and pure chromium in proteinaceous media: an electrochemical characterization

“…Some published papers I- [5][6][7][8] show that the inclusion of proteins in standard in vitro test solutions is important for the determination of the corrosion resistance of metals and alloys. Nevertheless, further work must be performed in order to answer the questions raised, such as which particular proteins influence the process, at which conditions and concentrations, is corrosion enhanced or inhibited, how differently do materials behave, what happens to the surface, what kind of corrosion products are generated and what is the actual mechanism by which proteins interfere in the degradation of metallic medical devices?…”

Electrochemical Performance of Fe40Al-X (X = Cr, Ti, Co, Ni) Alloys Exposed to Artificial Saliva

“…According to reported studies [45,48,49], in acid and neutral solutions, Co shows an active dissolution behavior forming cobaltous ions (Co 2+ ) according to the following reaction:…”

Material Selection Impact on Intraoperative Spine Manipulation and Post-op Correction Maintenance

“…Corrosion is material degradation due to reactions with its surrounding environment, which can ultimately lead to hardware failure (Singh and Dahotre 2007;Ratner et al 2004). As the human body is composed of an aqueous saline solution with numerous cations and anions, it is considered quite corrosive and so corrosion resistance is one of the main features of biocompatibility (Pan et al 1996;Lin and Bumgardner 2004;Williams and Clark 1982;Hallab et al 2000;Brown 1981, 1985;Baboian 2005). Interaction between different metal implants can also lead to corrosion.…”
