Abstract
We have discovered that the formation of particulate inclusions at the surface and the interior of an aluminum alloy article interferes with the performance of the article when a surface of the article is protected by an anodized coating. We have also discovered that the formation of such particulate inclusions can be controlled to a large extent by controlling the concentration of particular impurities present in the alloy used to fabricate the aluminum alloy article.
