Description The role of indium on the corrosion potential of high purity Al (99.999%) and commercial purity Al (99.33%)has been investigated, employing potential vs time, polarization and wavelength dispersive X-ray analysis (WDX) techniques. Indium has been found to shift the corrosion potential of Al towards either anodic or cathodic direction depending on the purity of Al providing an optimum value for cathodic protection of steel. WDX analysis shows that in Al containing Fe, indium reduces the cathodic activity of phases such as Al3Fe. In high purity Al, the deposited indium provides additional cathodic sites. These processes are responsible for lowering E-corr of commercial purity Al on the one hand and increasing E-corr of high purity Al on the other hand through simply alloying aluminum of various purity with indium.
