A SnO 2 -doped dicalcium phosphate coating was prepared on AZ31 alloy by means of hydrothermal deposition. The results showed that the coating possessed a globular morphology with a long lamellar crystalline structure and a thickness of approximately 40 μm. The surface of the coating became smooth with an increase additive amount of the SnO 2 nanoparticles. The corrosion current density and hydrogen evolution rate of the coating prepared in presence of SnO 2 were reduced compared to the coating without SnO 2 and the bare AZ31 substrate, indicating an improvement in the corrosion resistance of the SnO 2 -doped coating.
