- •
The PVPA-modified Ti6Al4V/PTFE interface shows anti-wear properties.
- •
The velocity-independent tribological behaviors from 0.3 mm/s to 48 mm/s are mainly owing to the robust PVPA chains and compatibility of two tribo-pairs.
- •
The good load-bearing capacity (63.49 MPa) of the thick PVPA coatings indicates their potential application in implants.
