AB  - Calcium phosphate (CaP) coatings were prepared on Mg-Zn-Zr magnesium alloy by 
      micro-arc oxidation (MAO) in electrolyte containing calcium acetate monohydrate 
      (CH3COO)2Ca.H2O) and different phosphates (i.e. disodium hydrogen phosphate 
      dodecahydrate (Na2HPO4.12H2O), sodium phosphate (Na3PO4.H2O) and sodium 
      hexametaphosphate((NaPO3)6)). Scanning electron microscope (SEM), 
      energy-dispersive X-ray spectrometry (EDS) and X-ray diffractometer (XRD) were 
      employed to characterize the microstructure, elemental distribution and phase 
      composition of the CaP coatings. Simulated body fluid (SBF) immersion test was 
      used to evaluate the coating bioactivity and degradability. Systemic toxicity 
      test was used to evaluate the coating biocompatibility. Fluoride ion selective 
      electrode (ISE) was used to measure F(-) ions concentration during 30 days SBF 
      immersion. The CaP coatings effectively reduced the corrosion rate and the 
      surfaces of CaP coatings were covered by a new layer formed of numerous 
      needle-like and scale-like apatites. The formation of these calcium phosphate 
      apatites indicates that the coatings have excellent bioactivity. The coatings 
      formed in (NaPO3)6-containging electrolyte exhibit thicker thickness, higher 
      adhesive strength, slower degradation rate, better apatite-inducing ability and 
      biocompatibility.
