The mechanical properties and corrosion behavior of double-layered nano hydroxyapatite-polymer coating on Mg-Ca alloy
Nano-hydroxyapatite (HA)/poly(e-caprolactone) (PCL) coatings with thickness of about 45-55 µm were prepared on the surface of a Mg-Ca alloy by a combination of electrochemical deposition and dip-coating methods. The results indicate that incorporation of nano-HA as an inner layer affects the porosit...

| description | Nano-hydroxyapatite (HA)/poly(e-caprolactone) (PCL) coatings with thickness of about 45-55 µm were prepared on the surface of a Mg-Ca alloy by a combination of electrochemical deposition and dip-coating methods. The results indicate that incorporation of nano-HA as an inner layer affects the porosity of the PCL-coated layer as top layer and enhances the corrosion resistance of Mg-Ca alloys. The nano-HA/PCL-coated samples showed higher Rp (823.1 kO cm2) and lower icorr (5.85E-2 µA/cm2) compared with uncoated. Significant enhancement in the compressive strength was observed in the both nano-HA/PCL and PCL compared with uncoated samples after 10 days immersion in SBF. |
