- Abstract
This paper provides a study for crystallographic orientation-dependent corrosion rate of aluminum employing an ab initio model with inputs from first-principles calculations. Results showed that the sequence of corrosion rate is in the order of (111) < (410) < (331) < (221) < (321) < (211) < (110) < (100) < (210) < (320) < (310) < (311) for aluminum. The predicted corrosion current densities for (111), (110), and (100) surfaces are in general agreement with the experimental results. The alloying effects were further investigated employing this model with results validated via the polarization curves of alloyed aluminum.
