Orthopedic and dental implants experience the synergistic effect of wear and corrosion, i.e., tribocorrosion, which has been a major contributor to the premature failure of implants. This work focuses on the development of a compact and cost-effective tribocorrosion apparatus for the investigation of fretting and wear. The custom-built apparatus is validated with an analysis of the tribocorrosion behavior of Ti–6Al–4V disks in artificial saliva (pH = 6.5, T = 37 °C). Electrochemical impedance spectroscopy, potentiodynamic, free potential, and potentiostatic analyses were used for electrochemical characterization of Ti–6Al–4V disks. White light interferometry and scanning electron microscopy were used to analyze wear scars on the Ti–6Al–4V disks. Total wear loss was calculated to be 12.4 ± 1.5 µg, and the synergistic weight loss ratio (0.78 ± 0.1) showed that Ti–6Al–4V disks experience synergy of wear and corrosion, with wear being the dominant component.
