The corrosion behavior of AXJ530 magnesium alloy has been investigated. Die‐cast and thixocast specimens were tested using potentiodynamic polarization, electrochemical noise analysis (ENA), electrochemical impedance spectroscopy (EIS) and immersion tests. These tests showed that all specimens were passive in that solution. However, the passive film formed on thixocast specimens was found to be more protective and resistant to localized corrosion than that of die‐cast specimens.
