Abstract

This study aims to design and process Ti–30Nb at% alloy with improved biocorrosion protection and lower elastic modulus for use as a bioimplant material in orthopedic applications. The influence of sintering temperature on phases, microstructure, microhardness, and modulus of elasticity was investigated. The surface energy of the alloy was evaluated and the bio-corrosion study was carried out in a simulated body medium. According to the findings, Ti–30Nb alloy consisted primarily of β-Ti, with traces of α-Ti and α” phases. Increasing the sintering temperature enhanced the density and microhardness. The developed Ti–30Nb alloys have a modulus of (55–78.9) GPa, which is lower than that of commercial Ti6Al4V alloy and CP-Ti. The surface energy of the designed Ti–30Nb alloys was 18.5% more than that of the commercial Ti6Al4V alloy. The obtained in vitro corrosion results confirmed the beneficial impact of sintering temperatures on the enhancement of the corrosion protection of binary Ti–30Nb alloy.
