A
powder metallurgy technique to fabricate silicon and magnesium-oxide coated magnesium-based bionanocomposite with
hydroxyapatite has been developed. The sample coated with double layer MgO/Si was compared with bare Mg/27.5HA
nanocomposite and the sample coated by Si layer only. The surface microstructure and the cross section of bare and coated
samples before and after corrosion were examined by field-emission scanning electron microscopy (FE-SEM). The corrosion
performance of bare and coated samples was evaluated using potentiodynamic polarization, electrochemical impedance
spectroscopy and immersion tests. A decrease from 4.28 to 0.65 mm/year was observed in corrosion rate of Mg/27.5HA
nanocomposite with monolayer Si-coating. The results indicated that the corrosion resistance of Mg/27.5HA nanocomposite
was significantly improved byMgO/Si double layer coating. Moreover, MgO/Si coating is promising to enhance biocompatibility
of Mg/27.5HA nanocomposite for implant application. Antibacterial tests of the bare and coated samples revealed their
antibacterial activity against Staphylococcus aureus and Escherichia coli.
