Abstract Scope |
To increase the longevity and to optimize the performance of biomedical implants, a new class of β-titanium alloys, specifically Ti-Nb-Zr (TNZ) is being explored. TNZ alloys demonstrate advantageous properties including non-toxicity, biocompatibility and low elastic modulii. Moreover, previous studies have shown that the addition of trace amounts of boron (0-1 wt.%) in titanium alloys increases the tensile strength and corrosion resistance of the alloys. However, the corrosion behavior of boron-containing TNZ alloys is yet to be investigated. Therefore, the objective of this study was to investigate the corrosion behavior of Ti-13Nb-13Zr (wt %) (Ti-1313) with 0.01, 0.1 to 1 wt% boron additions. Cast billets of TNZ alloys were hot isostatically pressed to reduce internal porosity. Materials were characterized using optical microscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The electrochemical characterization was carried out in accordance with ASTM standards. |
