Abstract

We investigated the inhibition by chromate ions of the localized corrosion of aluminum by electrochemical transient measurements. In agreement with other work, the measurements demonstrated that chromate is a cathodic inhibitor for aluminum in open circuit. The reduction of hexavalent chromium to trivalent chromium is assumed to take place on catalyzed sites of the surface. The resulting products inhibit oxygen reduction reactions at these sites, thereby retarding pitting corrosion.

Inhibition of pitting corrosion on aluminum alloy 2024-T3: Effect of soluble chromate additions vs. chromate conversion coating

Journal Article Ilevbare, G; Scully, J; Yuan, J; ... - Corrosion (Houston)

Pitting potentials (E{sub pit}) of aluminum alloy (AA) 2024-T3 (UNS A92024) were improved with additions of 0.01 M sodium chromate (Na{sub 2}CrO{sub 4}, pH 8) and 0.0062 M Na{sub 2}Cro{sub 4} + 0.0038 M chromic acid (H{sub 2}CrO{sub 4}, pH 6) additions to 0.1 M sodium sulfate (Na{sub 2}SO{sub 4}) + 0.005 M sodium chloride (NaCl, pH 6) after 2-h periods at open-circuit potential (OCP). Chromate conversion coatings (CCC) on AA 2024-T3 also improved E{sub pit} determined in fast potentiodynamic scans without periods at OCP. These tests were designed to minimize chromate leaching and long-range transport of chromate. The OCPmore »« less

A study of the inhibition of pitting of aluminum by chromate

Conference Hawkins, J; Thompson, G; Wood, G; ...

The location of chromate activity during the pitting corrosion of aluminum has been studied. Scanning vibrating probe technique monitored the current densities above cathodic and anodic sites and SIMS was used to determine the location of chromium reduction products. Products deposited preferentially on cathodes but chromates dramatically inhibited the anodic pitting processes. 8 refs., 3 figs.

Quantitative methods of predicting relative effectiveness of corrosion inhibitive coatings

Conference Aklian, J; Lewis, K; Zook, J

Results from several test methods are corroborated in predicting relative protection by non-chromate corrosion inhibitors in coatings for aircraft aluminum. Candidates are compared to both uninhibited and chromate-inhibited controls. Greater corroboration of results under a variety of test conditions gives greater confidence that new materials will protect aircraft aluminum alloys for the life of an aircraft, in a large range of exposure environments. Visually evaluated salt spray and filiform exposures used by the aerospace industry to judge the effectiveness of chromate-inhibited coatings, do not provide an adequate picture for non-chromates. Additional tests, electrochemical in nature, are needed and are suggestedmore »« less
Corrosion protection of aluminum metal-matrix composites

Journal Article Greene, H; Mansfeld, F - Corrosion

Corrosion protection of aluminum metal-matrix composites (MMC) by anodizing treatments was investigated. Electrochemical behavior of MMC without protection also was investigated. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements were used to characterize the properties of protective surface layers. Materials studied were Al 6061/SiC, alloy A356/SiC, Al 2009/SiC, Al 2014/Al{sub 2}O{sub 3} and Al 6061/Al{sub 2}O{sub 3} with various reinforcement concentrations. The MMC had similar corrosion (E{sub corr}) and pitting (E{sub pit}) potentials as the matrix alloy. The cathodic current density for oxygen reduction in 0.5% N sodium chloride increased for Al 6061/SiC MMC with reinforcement concentration, which was attributedmore »« less

Development of anodes for aluminum/air batteries: Solution phase inhibition of corrosion: Final report

Technical Report Macdonald, D.; English, C.; Urquidi-Macdonald, M.

Solution-phase inhibition is a promising strategy for controlling the corrosion of the aluminum fuel in alkaline aluminum/air batteries. Development of effective inhibitors would permit the use of scrap aluminum as fuel and thereby significantly improve the economics of the battery, because the cost of the fuel would have been partly or wholly defrayed by its previous use. In this study, we explored the discharge characteristics of aluminum in inhibited and uninhibited 4 M KOH at 50/degree/C and compared the performance of the fuel with that for two leading alloy fuels that had been evaluated in our previous work, Alloy BDWmore »« less
