IMPROVED TRIVALENT CHROMIUM-CONTAINING COMPOSITION FOR USE IN CORROSION RESISTANT COATING ON METAL SURFACES |
| 摘要 |
A low sludge trivalent chromium based conversion coating bath is provided which forms corrosion resistant coatings on aluminum and aluminum alloys by immersion in aqueous solutions containing trivalent chromium ions and fluorometallate ions followed by optional rinsing. Trivalent chromium coated aluminum also serves as an effective base for paint primers. |
