Crystallographic orientation dependence of corrosion behavior of a nickel-based single crystal alloy IN738 was studied. Potentiodynamic polarization and electrochemical impedance spectroscopy show that corrosion performance of the single crystal alloy varies with crystallographic orientation. The de...
