CORROSION-RESISTANT, MAGNESIUM-BASED PRODUCT EXHIBITING LUSTER OF BASE METAL AND METHOD FOR PRODUCING THE SAME |
摘要 |
<p>A corrosion-resistant article of a magnesium material having the gloss of the metal substrate surface comprises an anodic oxide film formed on the external surface of an article of magnesium or a magnesium alloy, which never changes the gloss of the metal substrate and a colorless or colored transparent electrodeposition coating film on the anodic film. Such an article can be prepared by immersing an article of magnesium or a magnesium alloy in an electrolyte containing a phosphate and an aluminate to thus form an anodic oxide film through anodization of the surface of the article and forming a colorless or colored transparent electrodeposition coating film on the anodic film through electrodeposition coating.</p> |
