Abstract
A SnO<sub>2</sub>-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<sub>2</sub> nanoparticles. The corrosion current density and hydrogen evolution rate of the coating prepared in presence of SnO<sub>2</sub> were reduced compared to the coating without SnO<sub>2</sub> and the bare AZ31 substrate, indicating an improvement in the corrosion resistance of the SnO<sub>2</sub>-doped coating.
