| Popis: | Titanium (Ti) and its alloys are widely used as implant materials because of excellent mechanical properties and corrosion resistance. In order to improve the bone bonding ability, titanium is generally coated with osteoconductive biomaterials such as CaP ceramics. The aim of the study was to investigate the effect of Mg-substitution on corrosion and bioactivity properties of CaP coatings on Ti6AlV substrates produced electro-deposition technique. Chemical and morphological characterizations of the coatings were examined by using X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Corrosion properties of the coatings were studied electrochemically by potentiodynamic polarization technique in simulated body fluid (SBF) at 36 +/- 1 degrees C. Additionally, bioactivity properties of the coatings investigated in SBF with varying time 1, 7 and 14 days. In conclusion, Mg-substitution enhances the bioactivity properties but does not have an affirmative effect on corrosion properties of the coatings. (C) 2016 Elsevier B.V. All rights reserved. |
