Magnesium alloys are characterized by unique properties and offer opportunities for lightweight applications. The challenge is to correlate the tensile and corrosion properties of the material to provide a holistic insight to its response to corrosion and monotonic loading. This paper presents extrapolating the various properties of the MgAZ91D alloy when it is subject the salt fog spray test. This process is suitable for automotive parts. The alloy composition microstructure and the character of the passive film capacity the corrosion mechanism of magnesium alloy exposed to aqueous solution and simulated saline atmosphere. Corrosion attack is disclosed between phases with different electro chemical behavior. FSP is an effective approach to refine the grain size and enhance the corrosion properties.
