Despite the well known biocompatibility and bioactivity of synthetic hydroxyapatite (HA), its use, as structural biomaterial has been limited because of intrinsic low mechanical properties. In order to avoid this problem, metallic implants are commonly coated with a thin HA layers. Among the various techniques used to produce coatings on metals, the biomimetic process has gained increasing attention in the last years. In this work, a metallic substrate (Ti6Al4V) was coated using a variation of the traditional biomimetic method. The HA coatings were characterised by diffused reflectance spectroscopy (DRIFT) and scanning electron microscopy (SEM).
