Construction of a Triboelectrochemical Setup with Controlled Environment for Biomaterial Testing with a Comparison of Cobalt–Chromium–Molybdenum and Titanium–Aluminium–Niobium Alloys

Abstract

The present work is focused on the manufacturing of a special self‐developed tribocorrosion setup with a controlled incubated environment. The comparative studies between wrought Co27Cr6Mo and Ti6Al7Nb alloys are performed with the respective tribometer in Ringer's solution at 37 °C. It is found that the CoCrMo alloy demonstrated a noble open circuit potential not only in non‐wear condition but also under wear conditions, in comparison to Ti6Al7Nb. The mass loss rate examined at open circuit potential and at a constant potential of 0.2 V versus Ag|AgCl|3.5 m KCl also suggests a similar superiority of the CoCrMo alloy.
