| Abstract: | The paper describes the results of examination of specimens after 10 years’ exposure to a very severe industrial atmosphere. The work is a continuation of tests previously reported by Whittaker and Kape. All anodized films show signs of pitting and the specimens have lost reflectivity to a marked extent. Resistance improves with increasing film thicknesses and higher purity of the aluminium. Periodic washing with distilled water does not decrease pitting or delay its onset. |
