    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: 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: 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: A system for electro-coating a metallic substrate includes a DC power supply, a primary electrode, and a wireless auxiliary electrode. The primary electrode transmits electrical current through electrolyte fluid when energized by the power supply. The auxiliary electrode is within the drain hole, and receives the current from the fluid at one end. The auxiliary electrode boosts the calibrated voltage at the opposite end near the drain hole. In a method for depositing thin film material onto the internal surfaces, the wireless auxiliary electrode is positioned in the drain hole, and the calibrated voltage is applied from the DC power supply to the primary electrode. Electrical current transmitted through the fluid is received at the first end of the auxiliary electrode. The calibrated voltage is boosted in proximity to the drain hole at the second end of the same auxiliary electrode. A wireless auxiliary electrode assembly is also provided.
