Abstract

One of the most promising techniques to deposit hydroxyapatite (HAP) coating is the biomimetic method. In this paper, different pretreatments $(HNO _{3,}$ 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.

Özet

Biomimetik yöntemle hidroksiapatit (HAP) kaplama en gelecek vaat eden tekniklerden birisidir. Bu çalışmada, üç farklı ön yüzey işlemi $(HNO _{3,}$ anodik polarizasyon, 5 N NaOH-1 N HCl (BA)) altlıkların (Ti ve Ti6Al4V) yüzey pürüzlülüğünü arttırmak için kullanılmıştır. Biomimetik apatit katmanlarının morfoloji, bileşim ve yapısı SEM, EDX ve FT-IR teknikleri ile incelenmiştir. 3xSBF’de 35 günlük daldırma sonrası yüzeyin tamamı apatit kaplama ile kaplanmıştır. SEM-EDX sonuçları kemikte bulunan tercihli yönlenme ve benzer bileşimin iyon bileşimi ve çözeltinin derişimine bağlı olarak biomimetik olarak sentezlendiğini göstermiştir. Kemik benzeri apatit katmanı sentezi, implantların biyoaktif yüzeylerini geliştirmek için bu biomimetik yöntemin etkin bir yol olduğunu göstermiştir. FT-IR analizi karakteristik HA absorpsiyon bantlarının sinterlenmiş yüzeyde oluştuğunu göstermiştir.
