Biomimetric coating of monophasic brushite on Ti6Al4V in new m-5xSBF
Source abstract
Abstract
Abstract Ti6Al4V plates were exposed to soaking alkali treatment resulted in Na0.23TiO2 phase on the surface before realizing biomimetic Calcium–Phosphate (CaP) coating in prepared m-5xSBF and 5xSBF solutions at 37 °C and pH 6. The aim of the present study was to examine CaP nucleation on the Ti6Al4V substrate in the new biomimetic medium, which allows the precipitation of uniform and monophasic CaPs coating within 2 days. Characterizations of coated surfaces were performed by SEM and EDX, FESEM, FTIR, Raman and contact angle measurements. Phase formation (Na0.23TiO2, 22-1404; TiO2, 21-1276; CaHPO4(H2O)2, 72-0713 and Ca5(PO4)3OH, 09-0432), average particle size distribution (0.1−1.8 μm for HA, 0.5−4.7 μm and 10.7−239.4 μm for width and length of Brushite), the specific surface area (85,623 and 1,169,412 m2 g−1 for Brushite and HA, respectively) and phase transformations (from brushite to calcium pyrophosphate) of the coated CaP powders on the surface were also examined by XRD, DLS technique, BET, and TGA, respectively. As a result, it has been possible to obtain for the first time monophasic brushite phase coated on Ti6Al4V in m-5xSBF biomimetic medium and monophasic brushite coated surface characterization was compared with hydroxyapatite coated surface obtained in 5xSBF.
