Effect of Aluminum Content on the Crevice Corrosion Behavior of Magnesium Alloys
In this work, the effect of aluminum content on the crevice corrosion behavior of the magnesium alloys has been investigated. The as-cast AZ31, AM60B and AZ80 alloys were subjected to the crevice corrosion in a freely aerated 3.5 wt.% NaCl solution, and the extent of the damage was quantified using...

description | In this work, the effect of aluminum content on the crevice corrosion behavior of the magnesium alloys has been investigated. The as-cast AZ31, AM60B and AZ80 alloys were subjected to the crevice corrosion in a freely aerated 3.5 wt.% NaCl solution, and the extent of the damage was quantified using weight loss measurement and 3D surface topography using an optical profilometer. The as-cast AM60B and AZ31 alloys exhibited the lowest and highest crevice corrosion resistances, respectively. The surface investigation using a scanning electron microscopy (SEM)/energy-dispersive spectroscopy (EDS) and analysis of the corrosion products by Raman spectroscopy, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) suggested that the corrosion damage predominantly was primarily a function of the volume fraction and distribution of the Mg
