Abstract
Mesoporous hydroxyapatite (HA) coatings were prepared on AZ31 magnesium (Mg) alloys by the sol-gel dip-coating method. The effect of mesoporous coating on the corrosion resistance of Mg alloy was investigated by the electrochemical and immersion tests in simulated body fluid (SBF), using the uncoated and non-mesoporous HA coated samples as control groups. The results showed that the mesoporous coating could provide effective protection to the Mg alloy substrate over the immersion period of 5 days. The introduction of mesoporous structure greatly decreased cracking of the coating in the immersion test and accelerated the apatite precipitation on the coating surface. Thereafter, the corrosion rate of mesoporous HA coated Mg alloy increased slowly as time evolved, being in line with the requirement of degradable implants.
