The role of pH on structure, corrosion behavior and biocompatibility of MgFe layered double hydroxide coating on Mg-Nd-Zn-Zr alloy.

In the present study, MgFe layered double hydroxide (LDHs) coatings were prepared on the surface of Mg-Nd-Zn-Zr (JDBM) alloy by a chemical conversion method, and the effects of the pH value (pH = 8, 10 and 12) of the prepared solution on the morphology, corrosion resistance and biocompatibility of the coatings were studied. The thickness of the Mg-Fe LDHs coatings was 43.79 ± 3.
