“…The non-uniformity of the structure of the cast Co-Cr alloy was confirmed by the standard deviation of the Vickers microhardness value. Similar to the present result, a few studies reported that casting technique can lead to poor mechanical properties compared to other manufacturing processes such as powder metallurgy and forging [3,4]. The corrosion resistance of cast and milled Co-Cr alloys was determined in artificial saliva solution using potentiodynamic polarization tests as shown in Fig.…”

In this study, the electrochemical behavior and tribocorrosion performance of cobalt-chromium (Co-Cr) alloys produced by different fabrication methods (casting and CAD/CAM milling technique) have been investigated in the laboratory-simulated artificial saliva. The results have shown that the maximum tribocorrosion resistance was obtained for milled Co-Cr alloy because of higher corrosion resistance and hardness of milled Co-Cr alloy compared too those of cast Co-Cr alloy. Moreover, the lowest friction coefficient was achieved for milled Co-Cr alloy.

“…The drop in OCP was lower for AISI 316 stainless steel than for Ti6Al4V alloy. (Doni et al, 2013). On veneering PEEK to Ti6Al4V, the evolution of OCP curve revealed a different behavior.…”

“…However, oblique loads can originate overloads on structural materials and on bone tissue that can promote failures by fatigue and wear of the implant-based system (Souza et al, 2015). Regarding the environmental conditions, several artificial saliva solutions have been used to study the corrosion and tribocorrosion behavior of dental materials (Souza et al, 2012(Souza et al, , 2015(Souza et al, , 2013Licausi et al, 2013;Mischler, 2008;Runa et al, 2013;Doni et al, 2013;Ponthiaux et al, 2004;Landolt, 2006). The formulation of artificial saliva solutions that react with the test material in a way similar to that of natural saliva is not easy to achieve in vitro, concerning the unstable properties of human saliva (Souza et al, 2015;Leung and Darvell, 1997).…”

“…Finally, the increasing impact and growing interest of biomedicine over the last decade have led to a great number of studies involving biomedical alloys used in orthopaedic and dental implants [2,[38][39][40], which are subjected to both corrosion and wear as a result of human activity. Biomedical materials such as the CoCrMo [41][42][43] alloy or titanium alloys [44][45][46] have been widely studied in simulated body fluids (SBF), e.g., artificial saliva, NaCl solutions, phosphate buffer saline (PBS) solutions, or foetal bovine serum (FBS) solutions.…”

This paper reviews the most recent available literature relating to the electrochemical techniques and test procedures employed to assess tribocorrosion behaviour of passive materials. Over the last few decades, interest in tribocorrosion studies has notably increased, and several electrochemical techniques have been adapted to be applied on tribocorrosion research. Until 2016, the only existing standard to study tribocorrosion and to determine the synergism between wear and corrosion was the ASTM G119. In 2016, the UNE 112086 standard was developed, based on a test protocol suggested by several authors to address the drawbacks of the ASTM G119 standard. Current knowledge on tribocorrosion has been acquired by combining different electrochemical techniques. This work compiles different test procedures and a combination of electrochemical techniques used by noteworthy researchers to assess tribocorrosion behaviour of passive materials. A brief insight is also provided into the electrochemical techniques and studies made by tribocorrosion researchers.
