Abstract

MXenes are a relatively new class of two-dimensional transition metal carbides, nitrides and carbonitrides experiencing increasing attention for tribological applications. Due to their multi-layer structure with relatively weak inter-layer bonding, a self-lubricating character is enabled. A possible, but not yet explored, application of MXenes is the addition to UHMWPE with the aim to improve the biotribological behavior of tibial inlays of total knee arthroplasties (TKA). Within this study, Ti₃C₂T_x-UHMWPE-composites with 0.5 wt.‑%, 1.0 wt.‑% and 2.0 wt.‑% MXenes were biotribologically tested using a pin-on-disk tribometer in oscillating sliding mode lubricated with diluted bovine calf serum at 37 °C. Thereby, a reduction of the coefficient of friction by up to 22 % compared to pure UHMWPE was demonstrated and the determined wear rates of the disks decreased considerably by 25 % (0.5 wt.‑% and 1.0 wt.‑%) and 43 % (2.0 wt.‑%). Furthermore, the composite-disks reduced the wear rates of the tested Co28Cr6Mo-pins by up to 19 %. Both the reduction of friction and wear show the great potential of MXenes as a reinforcement phase to UHMWPE to improve the biotribological behavior of tibial inlays and thus, increase the service life of TKA in the long-term.
