20090269501 | SELF-DEPOSITED COATINGS ON MAGNESIUM ALLOYS - 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.

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. | 10-29-2009 |
