Modification of the Electrochemical and Corrosion Behavior of Stainless Steels with an Electroactive Coating
TLDR
In this article, Electrochemical and SEM characterization results are presented, and effects of polyaniline coating application techniques are discussed, including the effect of localized corrosion on the open-circuit voltage.Abstract:
Electroactive polyaniline coatings have been deposited on ferritic stainless steels. The coatings appear to be deposited over the passive metal oxide film but can undergo electron transfer with the metal. Polyaniline immobilized on the alloys imparts a form of anodic protection which stabilizes the materials in mineral acids. Electrochemical and SEM characterization results are presented, and effects of coating application techniques are discussed. Oscillations in the open‐circuit voltage occur in solutions containing a high enough concentration of chloride ion to initiate pitting at potentials dictated by the coating. Inhibition of localized corrosion may also be obtainable for favorable systems.read more

Review of alternatives to chromate for corrosion protection of aluminum aerospace alloys
R. L. Twite,Gordon P. Bierwagen +1 more
TL;DR: The advent of chromate replacements for aluminum alloys began in the late 1970s as discussed by the authors, and commercial, academic and government facilities have relied on a collaborative effort to come up with novel innovations for the corrosion protection of aerospace aluminum alloy.
