The Crystal Orientation of Hydroxyapatite Coatings Affected by the Magnetic Fields on Magnesium Alloy

Abstract:

Hydroxyapatite coatings with biological activity on magnesium alloy can effectively reduce its degradation rate in the physiological environment. Pre-calcification was applied as the pretreatment in this paper. And then, hydroxyapatite coatings were deposited on the surface of the magnesium alloy in non-magnetic field, near the antarctic and the arctic of a constant magnetic field respectively. The morphology, phase composition and crystal structure of the coatings were analyzed using SEM and XRD. The results show that the crystals of the coatings affected by the magnetic fields are preferential orientation significantly.
