Tribological Behaviour of Ti6Al4V Alloy: An Application in Small Joint Implants
Popis výsledku v původním jazyce
The presented study deals with the analysis of the tribological behaviour of the Ti6Al4V alloy manufactured conventionally. The study aimed to verify whether the titanium alloy is suitable for use as a contact material in small joint implants, as additive manufacturing of this alloy can in the future provide certain benefits, such as individualization and simplification of the implant construction, or controlled porosity. The tested pair consisted of a pin and a glass plate lubricated with model synovial fluid. The contact area was observed with colorimetric interferometry. Alongside film thickness, friction, and wear scars were measured. From the designed experimental conditions, the titanium alloy was not able to create a sufficiently thick lubrication film to overcome its surface roughness and damage to contact surfaces occurred. Friction was comparable for all the tested configurations. The application of conventionally manufactured titanium alloy as a contact surface in small joint implants seems to not be suitable since its performance fell short when compared to conventional cobaltous alloy. Nevertheless, there are various alternative methods available, such as unconventional manufacturing, polishing, surface texturing, and coating.
