Paper Title:
Mechanical and Corrosion Properties of Titanium–Hydroxyapatite Nanocomposites
  Abstract

In the present work Ti-HA (3, 10, 20, 50 vol%) nanocomposites were produced by the combination of mechanical alloying and powder metallurgical process. The experimental results show, that Ti-HA nanocomposites have better mechanical and corrosion properties in comparison with microcrystalline titanium. For example: Vickers microhardness of Ti-10 vol% HA nanocomposite is 1500 HV0.2 (pure Ti metal – 250 HV0.2) and corrosion resistance in Ringer solution is Ic = 1.19 • 10-7 A/cm2, Ec = -0.41 V for Ti-10 vol% HA and Ic = 1.31 • 10-5 A/cm2, Ec = -0.36 V for Ti. In conclusion, titanium – ceramics nanocomposite are suitable for hard tissue replacement from the point of view of both mechanical and corrosion properties.
