2. Fig 1
Examinations of titanium sternal wire. (A) Scanning electron microscopy of an explanted titanium sternal. Most of the surface is seriously corroded at the grain boundary. (B) Higher magnification of figure part A. Scratches along the direction of drawing (double-headed black arrow indicates drawing direction on the manufacturing process of the titanium wire) are found on most grains and small crevices, and slip lines (white arrowheads) formed during plastic deformation are also observed on the grains. (C) The surface of an unused titanium wire from the same company shows scratches from drawing (double-headed black arrow indicates drawing direction). (D) Energy dispersive spectroscopy identifies titanium as the only component of the explanted wire with grade 2 purity. (E) Polarization curve shows that the explanted wire maintains satisfactory corrosion resistance similar to commercially pure titanium. (E/V vs. SCE = potential voltage (E) versus saturated calomel electrode.)
