Effects of phosphates on microstructure and bioactivity of micro-arc oxidized calcium phosphate coatings on Mg-Zn-Zr magnesium alloy

- Bioactive CaP coatings are successfully formed on ZK60 magnesium alloy.
- Different phosphates do not change the phases of CaP coatings.
- Fluorides released during the SBF immersion do not cause observed adverse effect.
- CaP coatings E3 show lower degradation rate, better bioactivity and biocompatibility.
