Abstract. Magnesium alloy ZK60 is a biocompatible and biodegradable material that has gained attention for its potential use in biomedical applications due to its high mechanical strength, lightweight properties, and biocompatibility. However, the high chemical reactivity and poor resistance to corrosion of magnesium alloys limit their use. This study evaluates the results from a potentiodynamic polarization test (PD) on ZK60 with surface treatments of plasma electrolytic oxidation (PEO) and PEO+PVA (Polyvinyl Alcohol with Glycerin). The aim is to understand the impact of these treatments on the corrosion behavior of ZK60 and to improve its properties for medical applications. The results showed that the PEO surface treatment significantly improved the corrosion resistance of ZK60, and the combination of PEO and PVA resulted in further improved corrosion behavior. This study highlights the potential of PEO and PEO+PVA treatments for improving the corrosion resistance of ZK60 and its suitability for use in biomedical applications.
