The aim of this work was to study tribological behavior and biological response of selective laser-melted Ti6Al7Nb-based TiB-reinforced composites. The synergistic properties achieved by different content of the in situ TiB phase (1.5 and 3.0 wt%) enhanced the wear resistance of Ti6Al7Nb. Abrasion and microplastic deformations were the predominant wear mechanisms observed in these composites. The contact angle of simulated body fluid on TiB-reinforced sample surfaces revealed that the surfaces were moderately hydrophilic. In vitro cell studies with pre-osteoblasts confirmed the non-toxic nature of all the three samples (matrix—Ti6Al7Nb, 1.5, and 3.0 wt% TiB composites) studied here. The enhanced wear resistance coupled with its non-toxic nature and good cell proliferation demonstrated that the Ti6Al7Nb–TiB composites are promising candidates for the fabrication of biomedical implants. In addition, the results demonstrate that Ti6Al7Nb composites can be easily fabricated by solidification-based additive manufacturing processes.
