Abstract
Reinforced crucibles for melting titanium alloys having a facecoat including at least one facecoat layer, a backing including at least one backing layer, and at least one reinforcing element applied to at least a portion of one or more of the facecoat layer, the backing layer, or a combination thereof where the reinforcing element includes at least one composition selected from ceramic compositions, metallic compositions, and combinations thereof.
Claims18
A reinforced crucible for melting titanium alloys comprising:
- a facecoat including at least one facecoat layer comprising an oxide selected from the group consisting of scandium oxide, yttrium oxide, hafnium oxide, a lanthanide series oxide, and combinations thereof;
- a backing including at least one backing layer;
- and
- at least one reinforcing element applied to at least a portion of one or more of the facecoat layer, the backing layer, or a combination thereof
- wherein the reinforcing element comprises at least one composition selected from the group consisting of ceramic compositions, metallic compositions, and combinations thereof.
