Abstract: (240 Views)
The main objective of the present study was to apply a polymer coating made of Polycaprolactone/chitosan (PCL/Ch) /1%wt. Baghdadite to an anodized AZ91 alloy through the immersion method in an attempt to improve these alloy's resistance to corrosion, bioactivity, and biocompatibility. The results of the corrosion test were indicative of an improvement in the corrosion resistance and a 103-fold decrease in the corrosion current density of the anodized AZ91 alloy as a result of applying the polymer-ceramic coating. Moreover, applied the polymer-ceramic coating increased the roughness of AZ91 from 0.329 ± 0.02 to 7.792 ± 0.34 μm. Simulated body fluid (SBF) was used to evaluate the apatite formation ability of the samples. The results showed the formation of an apatite layer on the sample surface which can be considered as a bioactivity criterion.
