| Abstract: |
| Nano hydroxyapatite (n-HAP) was coated on to AZ31 magnesium alloy in order to reduce the surface corrosion rate and enhance the bio-compatibility. N-HAP was successfully coated by pulse electrodeposition technique. Morphology and composition of the coatings were investigated by scanning electron microscopy and X-ray diffraction methods, respectively. The corrosion behaviors of the coatings were studied by tafel polarization and impedance spectroscopy tests. Results demonstrated that the porosity of the nano structure coating decrease in comparison with micro structure coating and therefore, corrosion resistance of AZ31 was improved significantly. Also, the adhesion of nano structure coating was increased and thus it can be introduced as a suitable coating for body implants. |
