Inhibition effect of cerium in hybrid sol–gel films on aluminium alloy AA2024†
Aluminium alloys such as AA2024 are susceptible to severe corrosion attack in aggressive solutions (e.g. chlorides). Conversion coatings, like chromate, or rare earth conversion coatings are usually applied in order to improve corrosion behaviour of aluminium alloys. Methacrylate-based hybrid films deposited with sol–gel technique might be an alternative to conversion coatings. Barrier properti...
متن کاملThe corrosion protection of AA2024-T3 aluminium alloy by leaching of lithium-containing salts from organic coatings.
Lithium carbonate and lithium oxalate were incorporated as leachable corrosion inhibitors in model organic coatings for the protection of AA2024-T3. The coated samples were artificially damaged with a scribe. It was found that the lithium-salts are able to leach from the organic coating and form a protective layer in the scribe on AA2024-T3 under neutral salt spray conditions. The present paper...
متن کاملControlled Fabrication of Nanoporous Oxide Layers on Zircaloy by Anodization
We have presented a mechanism to explain why the resulting oxide morphology becomes a porous or a tubular nanostructure when a zircaloy is electrochemically anodized. A porous zirconium oxide nanostructure is always formed at an initial anodization stage, but the degree of interpore dissolution determines whether the final morphology is nanoporous or nanotubular. The interpore dissolution rate ...
