Corrosion Properties of nTi, cpTi and Ti6Al4V in Simulated Body Fluid

The main aim of this contribution is determination of corrosion behaviour of titanium alloys, mainly ultra-fine grained titanium UFG (nTi) under simulated body fluid conditions at two different temperatures. Extrapolation by Tafel method pointed out on the fact, that corrosion resistance of nTi is better than of commercially pure (cpTi) at laboratory temperature. Actual rates of corrosion of titanium alloys markedly changes reaching human body temperatures.
