Effect of chromium on the electrochemical properties of iron aluminide intermetallics
Source abstract
Abstract
Abstract The effect of chromium content on the electrochemical properties of Fe 3 Al intermetallics is examined. The susceptibility of alloys to pitting and crevice corrosion in solutions with different concentrations of Cl − ions was studied with the aid of cyclic polarization and galvanostatic methods. The form of the pits, and their concentration on different crystal orientations, was evaluated with the Scanning Electron Microscopy (SEM) and Electron Backscatter Diffraction (EBSD) techniques. Additionally, Electrochemical Impedance Spectroscopy (EIS) and the Mott–Schottky (MS) methods were used to characterize the passive film. The results show the beneficial effect of Cr for corrosion and hydrogen embrittlement resistance.
