摘要： A method is disclosed for forming a clear anodized coating on an aluminum base alloy containing more than three percent by weight magnesium. The alloy surface to be anodized is treated with an aqueous solution of a mineral acid such as sulfuric acid (10 to 20%), nitric acid (10 to 30%) or phosphoric acid (40 to 80%) under the influence of a relatively low voltage direct current. This treatment suitably reduces the magnesium content of the surface layer and, subsequently, a relatively low current density anodization in sulfuric acid produces the clear coating. The clear coating may then be colored by known processes.

摘要： A process is disclosed for stabilizing certain colored anodized coating on aluminum articles against degradation by ultraviolet radiation. Anodized articles colored by an electrolytic or interference process can thereafter be stabilized by heat treating them at temperatures of the order of 350° F. for a period of an hour or so. The process is particularly useful for use on electrolytically colored, anodized vehicular external body panels made from suitably formable sheet metal aluminum alloys.

摘要： Some articles such as automobile components that have been constructed from steel and/or aluminum alloy parts are now being fitted with magnesium parts whose surfaces may need to be protected against corrosion. To do this an e-coating pre-film may be formed on the part's magnesium surfaces by exposing it to a conventional e-coating emulsion. And there is no need to supply a current or potential to the part or component. Magnesium's high reactivity with acidic or neutral aqueous mediums is itself a sufficient driving force to facilitate the deposition of an e-coating pre-film. At the same time any steel or aluminum alloy parts will remain unaffected. The article with a protective e-coating pre-film formed solely on its magnesium surfaces may now be advanced through a paint-line that includes conventional processes aimed at treating the component's steel and aluminum alloy parts. The process may be practiced where the magnesium surface comprises a magnesium-containing conversion or anodized coating.
摘要翻译： 一些由钢和/或铝合金部件构成的汽车部件的物品现在配备了可能需要防止其表面腐蚀的镁部件。 为了做到这一点，可以通过将其暴露于常规的电泳涂布乳液，在该部件的镁表面上形成e涂层预膜。 并且不需要为零件或部件提供电流或电位。 镁与酸性或中性水性介质的高反应性本身是促进电镀膜预膜沉积的足够驱动力。 同时任何钢或铝合金零件都不会受到影响。 具有仅在其镁表面形成的保护性电镀涂层预薄膜的物品现在可以通过涂料线进行，其包括旨在处理组分的钢和铝合金部件的常规方法。 该方法可以在镁表面包含含镁转化或阳极化涂层的情况下进行。

摘要： The present invention uses a two-step anodizing process to produce a colored anodized coating on the surface of an aluminum part. In accordance with this invention, a thin hard anodized coating layer is first formed on the surface of the aluminum part and then growing a softer a clear anodized coating layer on the surface of the aluminum part underneath the hard coat layer. The soft coat is essentially colorless and suitable for color finishing. This invention drastically improves the wear resistance of the aluminum part while maintaining a desired amount of clarity for effective electrolytic coloring.

摘要： Mixed-metal automotive vehicle bodies-in-white comprising ferrous metal surfaces, zinc surfaces, aluminum alloy surfaces, and magnesium alloy surfaces are cleaned and immersed in an aqueous bath comprising an adhesion promoter and an aqueous electrocoat bath (the adhesion promoter may be in the electrocoat bath. The adhesion promoter, which may be a cerium salt, is selected to react with each metal in the body surfaces to form an oxide layer that provides corrosion resistance for the surface and adherence for the deposited polymeric paint coating. The body is cathodic in the electrocoat deposition.
