Calcium phosphate-titanium mixture layers prepared with the assistance of an oxygen ion beam: The effect of titanium dopant on surface chemistry, mechanical properties, electrochemical behaviour and SaOs-2 cell colonization

Popis výsledku v původním jazyce

We present a study of the effect of titanium on the microstructure and properties of calcium phosphate-titanium mixture layers. The mixture layers were deposited by dual electron beam evaporation of calcium phosphate and titanium with the assistance of an oxygen ion beam. The addition of titanium resulted in a mixture of phosphate compounds, titanium dioxide and titanium with an amorphous/nanocrystalline nature. The rising formation of titanium oxides with titanium doping significantly enhances the mechanical properties and reduces the coefficient of friction. The changes in surface chemistry and roughness with the amount of titanium in the structure lead to an increase in the contact angle, and the wettability tends to shift from hydrophilic behavior to hydrophobic behavior. Titanium doping increased the corrosion resistance of the mixture layers in a physiological saline solution. The slowed solubility of titanium-richer mixture layers prevented local supersaturation of the culture medium, and led to enhanced surface colonization by SaOs-2 cells. The calcium phosphate-titanium mixture layers deposited with oxygen ion assistance that are presented here can be a promising composite material for tuning the surface properties of biomaterials.
