Beta-Ti alloys are being developed for novel load-bearing implants owing to their low elastic moduli and biocompatible compositions. We report on additive manufacturing of near-beta Ti-13Nb-13Zr alloy using laser powder bed fusion (LPBF). A wide range of LPBF parameters was employed to achieve relative part densities > 99 %. Low input energy parameters lead to the formation of martensitic alpha microstructure with < 1 % beta phase fraction. Further improved states were obtained via standard capability aging, super-transus (900°C) and sub-transus (660°C) heat treatments with quenching, thus inducing various fractions of martensitic alpha (alpha’, alpha’’) phases and of beta phase. LPBF and 900°C treatments yielded specimens with the best combination of enhanced tensile properties, good ductility and low Young’s moduli of 73-78 GPa. All alloy states revealed excellent corrosion resistance in a synthetic biofluid (PBS). For enhancing their surface biofunctionality, LPBF-Ti13Nb-13Zr specimens were subjected to laser texturing using Direct Laser Interference Patterning (DLIP) with nanosecond (ns) and picosecond (ps) pulses, forming single-scale and multi-scale topographies. Multiscale surface chemical and microstructural analyses of those DLIP states helped in understanding the corrosion behavior in PBS. Increased beta-phase fractions and uniformly thick passive layers of ns-DLIP surfaces led to enhanced corrosion stability compared to ps-DLIP with defective surface oxide. Both DLIP states control the surface wettability, thereby limiting corrosion and metal ion release rates, which is beneficial for implant applications. In vitro studies with bone marrow stromal cells (hBMSC) revealed, how those tailored surface topographies can guide cell attachment, and in consequence proliferation and differentiation.
