Calcium phosphate slurry (CP-Slurry) is used for fabricating a thin hydroxyapatite (HAp) coating on titanium (Ti) by a chemical coating process. A titanium (Ti) substrate was completely buried in CP-Slurry prepared by mixing calcium phosphate powder (CP-Powder) with distilled water, and the substrate was then heated at 973 K in air. The fabricated coating consisted of HAP and titanium dioxide (TiO2), and the thickness of the coating was approximately 300 nm. When the coated Ti was soaked in a simulated body fluid, a calcium phosphate precipitate grew on its surface within 1 day. The chemical coating process using the CP-Slurry is a promising technique for enhancing the bioactivity of Ti. (C) 2011 Elsevier BM. All rights reserved.
