Corrosion resistance of a novel SnO(2)-doped dicalcium phosphate coating on AZ31 magnesium alloy

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 w...

Sumario: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.
