... minutes into the dry air purge after 8 days of testing. This change in potential was attributed to the impact of relative humidity on electrolyte film thickness and cathodic kinetics. ASTM G85-A2 Aluminum Lithium Alloy 2060 Exfoliation Salt Spray Testing INTRODUCTION Accelerated laboratory testing...

... system. Significant attack at the scribe was observed on both sets of specimens. Underfilm attack at the scribe was essentially a function of time in the salt spray test. The longer the salt spray test, the greater the penetration at the scribe. Previous experience with wash primer as a pretreatment...

...). CONCLUSIONS On the basis of the 168 hour salt spray test, it has been shown that although trivalent chromium conversion coatings are much more effective corrosion inhibitors for aluminum 2024-T3 alloys than various tested ORMOSIL films, these layers fail to prevent the corrosion process completely...

... 1255 frequency response analyzer. Two impedance spectra were collected from separate locations on each panel. RESULTS AND DISCUSSION Salt spray test results Abstract The corrosion resistance of 33 different conversion coatings applied to five different aluminum alloys was tested by salt spray...

... self-healing at scribe The peroxide post-treatment only marginally improved the corrosion resistance and degree of self-healing on 7075-T6; marked improvement was noted for 2024-T3. All panels peroxide post-treated were able to pass the 336 hour salt spray test except for sprayed 2024-T3. 7075-T6...
