It is seen that some micro-pores appear on surface of the coating which soaked in SBF for 1 week. After 2 weeks, the coating degraded gradually. After 3 weeks, some fish bone-like tissues are found on the surface of the coating. After 4 weeks, the coating degrade further. After 5 weeks, the coating is further degraded and exposed loose structure like dendrite. 6 weeks later, the surface of the coating appears some large holes. Microporous and holes can increase the contact area of the surface in SBF and promote degradation of the coating.

It can be seen from the figure that some micro-holes appear on the coarse surface of the coating which soaked in SBF for 1 week.  After 2 weeks, the coating degrades gradually. After 3 weeks, some fish bone-like tissues are found on the surface. After 4 weeks, the coating surface degrades further,large blocks of honeycomb-like micro-holes appear. After 5 weeks, the coating surface further degrades and expose loose structure like dendrite. 6 weeks later, some large holes appears on the surface of the coating. Microporous and holes are helpful to increase the contact area between the coating and the simulated liquid, and promote the further degradation of the coating.
