Abstract

The aim of this paper is to compare the bioactive behavior generated by two different surface treatments on Ti-6Al-7Nb previous to the implant in the animal knee. One of the treatments consists in soak the sample with NaOH and followed by a subsequent heat treatment. The other treatment consists in immersion for 19 days in a SBF solution with additional PAW1 biovitroceramic (particles under 20 µm) content at 36 ºC. After a long exposure (more than 100 days) of the samples to a simulated body fluid, the surfaces were investigated to clarify what bioactive structure forms on the alloy and how it changes in the body’s environment. A knee plate was design for the samples of Ti-6Al-7Nb.
