Process for surface treating magnesium alloy and article made with same |
摘要 |
A process for treating the surface of magnesium alloy comprises providing a substrate made of magnesium alloy. The substrate is then treated with a chemical conversion treatment solution containing cerium nitrate and potassium permanganate as main film forming agents, to form a cerium conversion film on the substrate. A ceramic coating comprising refractory metal compound is next formed on the cerium conversion film by physical vapor deposition. |

1. An article, comprising:
a substrate made of magnesium alloy; a cerium conversion film directly formed on and in contact with the substrate, the cerium conversion film being formed by chemical conversion treatment with a chemical conversion treatment solution containing cerium nitrate and potassium permanganate as main film forming agents, the cerium conversion film comprising hydroxide of trivalent cerium, hydroxide of tetravalent cerium, hydroxide of divalent manganese, oxide of trivalent cerium, oxide of tetravalent cerium, and oxide of divalent manganese; and a ceramic coating comprising refractory metal compound directly formed on and in contact with the cerium conversion film by physical vapor deposition. |
