“…This effect has also been observed in biotribocorrosion studies, where the metal ion release under wear-corrosion conditions of the human body critically depends on the electrode potential, as confirmed by Espallargas et al (2015) [63]. On the other hand, the proteins present in human body fluids have been found to have a beneficial effect on the tribocorrosion response for biomedical materials.…”

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.

“…Cyclic polarization curves of the CoCrMo alloy showed similar behaviors. The passive region of the specimen tested inside DMEM was slightly longer but the passive current densities and breakdown potentials of alloy were almost the same and independent of solution chemistry . Polarization curves of CP‐Ti specimens were almost the same expect for a slight difference in potential values.…”

Corrosion behavior is an important parameter for metallic biomaterials used in the body environment. To mimic bodily fluids, simulated body fluid (SBF) has been used extensively. Even though many studies focus on corrosion inside SBF, SBF has a very time consuming and delicate preparation procedure and contains no essential and organic components for the cell environment, which may affect corrosion kinetics. We aimed to investigate whether corrosion behavior or kinetics change in different solutions, SBF and Dulbecco's modified Eagle medium (DMEM). For this purpose, five commonly used metallic biomaterials, AISI 316 stainless steel, CoCrMo alloy, CP‐Ti, Ti6Al4V, and Ti6Al7Nb were subjected to open circuit measurements, cyclic polarization, and electrochemical impedance spectroscopy. Quantitative analyses were performed and surface topography was investigated via scanning electron microscope and a roughness tester. We observed that the materials exhibited similar behaviors in SBF and DMEM but the corrosion kinetics were somewhat different and the results obtained from DMEM were time dependent.

“…Therefore, corrosion in instrumentation must be beyond galvanic corrosion. It has been our experience, that the corrosion coupling of Ti6Al4V and CoCrMoC alloys is predominantly a wear function where fretting between parts continuously exposes pristine substrate alloy to the surrounding body fluids (electrolyte), called tribocorrosion [7]. In previous cases, we have observed the presence of particles or elements present on opposing surfaces present on all components, however, this phenomenon only appears to occur where fretting occurs.…”

“…The corrosion of metal alloys (A316L Surgical stainless steel; ASTM F136 ELI Ti6Al4V; ASTM F75/F1537/F799 CoCrMoC) in-vivo has also been well documented [5][6][7][8]. Proprionibacterium acnes as well as Staphylococcus Epidermis are considered sulfur reducing bacteria in the petroleum industry and have been found in petroleum stockpiles and pipelines [9,10].…”
