英文摘要	A hydrid coating composed of dicalcium phosphate dihydrate (DCPD) and poly(lactic-co-glycolic acid) (PLGA) is prepared on AZ31 Mg alloy to control the corrosion resistance. The DCPD coating is deposited on the A231 substrate by electrochemical deposition and subsequently covered by the PLGA coating. Poten-tiodynamic and electrochemical impedance spectroscopy (EIS) tests conducted in simulated body fluid at 37 degrees C indicate that the corrosion resistance of the AZ31 is improved significantly by this hybrid coating. The deposition time influences the morphology and structure of the DCPD coating and consequently affects the corrosion resistance of both the DCPD and DCPD/PLGA coated samples. (C) 2015 Elsevier Ltd.
