Cu-rich aluminum alloys such as AA2024-T3 are widely used in the aerospace industry.  Corrosion inhibition coatings are important in the use of these alloys.  A key to the corrosion of AA2024-T3, is the ability of intermetallic particles to reduce 02.  We describe a new coating formulation that significantly inhibits 02 reduction at AA2024-T3 based on self-assembling zirconium phosphonate coatings.  Coating of samples is achieved by immersion of the alloy sequentially in non-aqueous phosphonate-containing solutions and aqueous solutions of zirconyl nitrate.  This method relies upon the adsorption of phosphonate species on the oxide surfaces, such as the Al oxide species present on bulk AA2024-T3 as well as the ability for long alkyl chain phosphonates to form self-assembled monolayers (SAMs).  Characterization of the layers has been done using Auger electron spectroscopy (AES) with depth profiling, reflection FTIR and advancing contact angle measurements (ACA).  These coatings have shown significant decreases in the ability of IPs to participate in dioxygen reduction.  Current density reductions of up to two orders of magnitude on treated AA2024-T3 samples have been observed.  The most effective coating for the inhibition of the ORR, has been provided by the combination of Zr and octadecyl phosphonate (Zr-ODP).
