Abstract
A conductive element comprises a metal core and a coating, wherein the coating comprises at least one layer of aluminum, an aluminum alloy, an aluminide, silicon, a silicon alloy, a silicide, and combinations thereof, and wherein the at least one layer has a predetermined thickness. A method of making a conductive element comprises depositing a coating material on a metal core to form a coated metal core and heating the coated metal core to a predetermined temperature to form at least one layer of aluminum, an aluminum alloy, an aluminide, silicon, a silicon alloy, a silicide, and combinations thereof.

1-42. (canceled)
The method according to 47, wherein the metal core comprises a metal that from a group consisting of niobium, tungsten, molybdenum, combinations thereof, and alloys thereof.
The method according to 47, wherein the depositing comprises a method selected from the group consisting of chemical vapor deposition, physical vapor deposition, slurry coating, spray coating, pack cementation, and combinations thereof.
45-46. (canceled)
A method of making a conductive feedthrough for a lamp comprising a sealed envelope having a portion of the conductive feedthrough extending outside of the sealed envelope, the method comprising:
- depositing a slurry having at least one precursor of a coating material on a metal core such that the metal core is covered by the slurry;
- and
- heating the metal core covered by the slurry at a predetermined temperature in an inert atmosphere for a predetermined period of time to form a coating on the metal core.
