dc.description.abstractImplant materials often suffer from wear, surface degradation, and poor biocompatibility, leading to reduced durability and compromised patient outcomes. Addressing these challenges requires the development of advanced biomaterials with enhanced mechanical strength and bio-tribological performance. In this context, we explore the incorporation of multi-layer Ti3C2Tx into a 316L metal matrix to enhance mechanical and biotribological properties for biomedical applications. Metal matrix composites (MMCs) with 1, 2, and 3 wt.-% Ti3C2Tx were fabricated using laser powder bed fusion (LPBF). Mechanical properties, including surface roughness and hardness, and the bio-tribological behavior were evaluated under dry and synovial body fluid (SBF)-lubricated conditions at 37 ◦C. Lower Ti3C2Tx concentrations yielded smoother surfaces, while higher concentrations increased roughness due to particle agglomeration and clustering. However, the resulting hardness improved especially for an addition of 3 wt.-% Ti3C2Tx. The 1 wt.-% Ti3C2Tx MMCs reduced wear by 31 and 19 % under dry and SBF conditions, respectively, while balls wear (counter-bodies) were reduced by 51 and 13%, respectively. These results highlight the potential of multi-layer Ti3C2Tx to improve the durability and performance of medical devices, demonstrating their promise as advanced biomaterials.
