Influence of coating bath chemistry on biomimetic calcium phosphate coatings
Source abstract
Abstract
Magnesium alloys are an emerging class of biodegradable medical implant materials. However, control of their degradation rate and biocompatibility are key issues that need to be addressed prior to their use in clinical applications. In this article, a two-step method to biomimetically deposit corrosion-resistant calcium phosphate coatings on magnesium alloy AZ31 is described. A decrease in the overall dissolution of the magnesium substrate of up to 99·8% was observed for the coated samples in comparison with non-treated magnesium AZ31. Surface characterization of the coatings was performed by attenuated total reflectance–Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive spectroscopy and X-ray photoelectron spectroscopy. The results indicate that the composition, morphology and corrosion resistance of the biomimetic calcium phosphate coatings depend strongly on the coating bath composition.
