| Abstract Scope |
It is well known that Al-Mg alloys exhibit significant susceptibility to corrosion and stress corrosion cracking when exposed to marine environments. Recent experiments conducted on pure aluminum alloyed with Ce have shown increased resistance to corrosion, but the effect of Ce on corrosion behavior in engineering aluminum alloys like Al-Mg has not been rigorously studied. The objective of this study is to evaluate the corrosion resistance of three different as-cast Al-Mg-Ce alloys (Ce contents ranging from 2 to 8 wt. %) immersed in 0.6 M NaCl via open circuit and potentiodynamic measurements. These corrosion data are then correlated with the results of X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) measurements to understand microstructure-corrosion behavior relationships. Such information will then be used to inform the development of future alloy compositions and heat treatment protocols. |
