Designed Solution to Coat Titanium Sheets with Octacalcium Phosphate

Article Preview

Abstract:

In this work, a solution able to precipitate calcium phosphate in titanium samples was studied. At first, a thermodynamic analysis of the proposed solution was conducted using a computational simulator that considers most of chemical reactions and evaluates parameters such as activity of species. After this procedure, experimental tests were performed in order to confirm this precipitation. With the use of TRIS at concentration of 50mM, the deposits were basically composed of octacalcium phosphate, as confirmed in some characterization techniques. The deposit presents a thickness of approximately 15μm after a 7-day exposure in the designed solution.
