Abstrak

The oxide coatings were produced on AZ31B Mg alloy using plasma electrolytic oxidation (PEO) process in alkaline electrolyte with and without addition of starch. The properties and surface morphologies of the PEO coatings were studied by voltage—time curves, scanning electron microscopy (SEM), X-ray diffraction (XRD) and potentiodynamic polarization, respectively. It was found that the coating formed in the electrolyte with starch has more compact and uniform morphology than that formed in the electrolyte without starch. The XRD analysis showed that the compositions of coatings formed in the electrolytes with and without starch are almost the same, containing MgO, MgSiO3, and Mg2SiO4. The results of potentiodynamic polarization tests showed that the coating formed in the electrolyte with starch enhanced the anti-corrosion characteristic.
