Abstract One of the most promising techniques to deposit hydroxyapatite (HAP) coating is the biomimetic method. In this paper, different pretreatments (HNO3, anodic polarization, 5 N NaOH-1 N HCl (BA)) were used to increase surface roughness of the substrates (Ti ve Ti6Al4V). The morphology, composition and structure of the biomimetic apatite layers were investigated with SEM,EDX and FT-IR techniques. The entire surface after immersed for 35 days in 3xSBF was covered by an apatite coating. The SEM-EDX results show that apatite layers with preferred orientation and composition similar to that found in bone can be biomimetically synthesized depending on the ion composition and concentration of the solution. It was shown that this biomimetic synthesis of a bone-like apatite layer may be an effective way to produce bioactive surfaces of implants. FT-IR analysis shows that characteristic HA absorption bands have occurred the sintered surface. Key words: Titanium, biomimetic method, HAP coatings, SBF, apatite
