“…During friction, dissipated energy was the greatest at the initial stage of the test, which corresponded to the area of active solubilization of the metal (1,2). For passivation potentials (3,4), the energy decreased slightly, and it reached its lowest values within the transpassive range (5). Observed energy dependencies may be linked to electrochemical processes occurring on the surface of the tested alloy, affecting the operational lifetime of the surface layer.…”

“…Due to the toxicity of vanadium, which causes osteolysis, inflammatory states as well as carcinogenic changes [4], new alloy compositions (Ti-6Al-7Nb, Ti-6Al-(3-6)Nb-(1-6)Ta, Ti-5Al-2.5Fe, Ti-12Mo-5Zr-3Al) with better biocompatibility are being created. Additives of Mo, Ta, and Nb stabilize the β-phase and improve their fatigue strength, corrosion resistance, and elastic modulus, which should be similar to the elastic modulus of human bone [5,6]. However, due to their high production costs, their involvement in medical applications is limited [7,8].…”

The paper presents the results of in vitro studies of fretting and fretting corrosion processes of Ti6Al4V implant alloy in the environment of natural saliva and self-made mucin-based artificial saliva solutions. The study was performed on a specially designed fretting pin-on-disc tester, which was combined with a set used for electrochemical research. The open circuit potential measurements and potentiodynamic method were used for corrosion tests. The worn surfaces were subjected to microscopic observations and an evaluation of wear. Results were interpreted using the dissipated energy and third-body approaches. The X-ray diffraction analysis showed that titanium oxides constitute over 80% of the friction products. Special attention was paid to the role of saliva and its substitutes, which in certain cases can lead to the intensification of fretting wear. On the basis of the received results, a new phenomenological model of fretting corrosion processes was proposed. This model involves the formation of an abrasive paste that is a combination of metal oxides and the organic components of saliva.

“…At potentials higher than +1500 mV vs. Ag/AgCl, there was an increase in anodic current densities for the three samples. It is suggested that the increase in current densities at the higher potentials is not the indication of transpassive phenomena (i.e., the destruction of the passive film by oxygen evolution) in titanium based alloys [35,36]. This was due to the formation of a new passive layer made of phosphorous containing titanium complex [31] in the stagnant PBS solution.…”

“…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.
