Abstract

The sol-gel chemistry route has been developed to prepare calcium phosphate / hydroxyapatite thin films on titanium substrate by dip-coating technique. The final composites were obtained by calcination of coatings for different time at 1 000 °C. It was shown that adjustment of heating time and dip-coating conditions can be used to control the synthesis processing, phase purity and morphology of thin films. It was concluded that the formation of calcium phosphate / hydroxyapatite composites in some cases is promoted by dipping time.
