Originální abstrakt

Plasma electrolytic oxidation (PEO) coatings with and without calcium phosphate (CaP) were prepared on AZ31 magnesium alloy including the CaP coating on AZ31 alloy. The microstructure of all coatings was characterized using an electron scanning microscope with energy dispersive spectroscopy (SEM/EDS). The PEO coating revealed the presence of many pores and microcracks on its surface. The deposition of CaP on the PEO layer led to the cover of these microstructural defects. Potentiodynamic polarization in 0.15 M NaCI medium showed that CaP/PEO, CaP and PEO coatings led to the improvement in the corrosion resistance when compared to bare AZ31 alloy. However, the corrosion resistance of CaP/PEO duplex coating was lower than PEO coating even though the CaP crystals covered the pores and microstructural defects. © METAL 2022. All rights reserved.
