Anodic Polarization Behavior of Iron-Aluminum Alloys in Sulphuric Acid.
Abstract
The anodic polarization of iron-aluminum alloys has been investigated by the potentiostatic technique in hydrogen saturated sulfuric acid solutions. All alloys containing up to 20 w/o aluminum exhibited active, passive and transpassive characteristics. An improvement in corrosion resistance was seen for alloys with aluminum content of more than 16 w/o which may be attributed to the ordered phase Fe3A1. Micrographs of the surface of anodically polarized alloy were examined at selected potentials, and the surface topography showed a significant difference in accordance with the reaction mechanism in each step of anodic polarization.
