Titanium is a successful biocompatible material that is used for biomedical applications, especially for bone-anchoring systems, such as dental and orthopaedic implants. It has advantageous bulk mechanical properties such as a low modulus of elasticity and passive surface properties such as excellent corrosion resistance, low rates ion released and a high degree of biocompatibility which is largely attributed to an inert surface oxide film. Hydroxyapatite is widely used as a bioactive ceramics since it forms a chemical bonding to bone. Applications include coatings of orthopedic and dental implants and scaffolds for bone growth. This work presents an alternative coating method based on biomimetic techniques which are designed to form a crystalline hydroxyapatite layer very similar to the process corresponding to the formation of natural bone. The hydroxyapatite deposits are investigated by means of scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). In vitro hydroxyapatite formation studies show that the morphology and structure of hydroxyapatite layers alter in different condition of preparation.
