Claims
- 1. An aluminum alloy article having a corrosion-resistant coating comprising lithium molybdate and cerium, wherein the lithium molybdate has been applied to the alloy, and then cerium has been applied to the lithium molybdate coated alloy.
- 2. The aluminum alloy article of claim 1, wherein the lithium molybdate and cerium are applied at a pH, measured at about 20° C., of about 10-11.
- 3. The aluminum alloy article of claim 1, wherein the lithium molybdate and ceruim are applied at a pH, measured at about 20° C., of about 10.5-11.
- 4. The aluminum alloy article of claim 1, wherein the lithium molybdate and cerium are applied by dipping the alloy article at a pH, measured at about 20° C., of about 10-11.
- 5. The aluminum alloy article of claim 1, wherein the lithium molybdate and cerium are applied by dipping the alloy article at a pH, measured at about 20° C., of about 10.5-10.75.
- 6. The aluminum alloy article of claim 1, wherein the lithium molybdate and cerium are applied by brushing at a pH of about 10-11.
- 7. The aluminum alloy article of claim 1, wherein the lithium molybdate and cerium are applied by brushing at a pH of about 10.5-11.
- 8. The invention of claim 1, wherein the cerium is part of a four valence cerium compound.
