Paper Title:
Apatite-Forming Ability Governing Bone-Bonding of Ti-15Zr-4Nb-4Ta Alloy Subjected to Calcium Solution Treatment
  Abstract

Ti-15Zr-4Nb-4Ta alloy is an attractive metal for orthopaedic implants, since it is free from cytotoxic elements and shows high mechanical strength. It was recently shown by an animal experiment [1] that this alloy tightly bonds to living bone, when it was subjected to 5 M NaOH solution and 100 mM CaCl2 solution treatments, heat treatment at 600 or 700 °C, and final water treatment at 80 °C. The bonding strength was increased markedly when the heat treatment temperature was increased from 600 to 700 °C. This increase of the bonding strength was attributed to the increase in apatite-forming ability of the treated alloy in a simulated body fluid (SBF) [2] with ion concentrations nearly equal to human blood plasma, although its reason was not revealed yet.
