Abstract

This study aims to evaluate the reduction of magnetic susceptibility depending on Zr element addition to the novel Ti-Mo-xZr alloy used for biomedical applications. Low magnetic susceptibility is essential for biomaterials to enable implant material to adapt inside the human body for a long time, prohibiting implant rejection and avoiding interference with the magnetic field through MRI examination. Zr addition to Ti-10Mo reduced magnetic susceptibility to a lower level than commercial Ti64 bio-implants (3.71×10−6 cm3/g), and TMZ6 alloy magnetic susceptibility (3.11×10-6 cm3/g) is lower than CP-Ti (3.38 ×10−6 cm3/g). Mo-equivalent and magnetic susceptibilities are claimed to be proportional inversely. The magnetization curves of entirely studied Ti-alloys are observed to maintain linearity, representing paramagnetic properties suitable for bio-implants and stable during MRI examinations. The results revealed that the addition of 6 wt.% Zr in Ti-Mo-xZr alloy reduces the magnetic susceptibilities from 3.088×10-6 to 2.967×10-6 cm3.g-1. Measured and calculated magnetic susceptibility obtained the same behavior as Zr addition with different slopes.
