Superalloy composite structure |
| abstract |
ABSTRACT Superalloys such as those with a nickel or cobalt-base reach their maximum practical operating temperature in the neigh-bourhood of 1000°C. Efforts have been made to raise this oper-ating temperature by using reinforcing materials such as filaments of tungsten or other strong refractory materials. Migration of alloy constituents into these filaments may have a detrimental effect on their strength. Coatings are proposed which prevent this migration. Such coatings may consist of materials such as hafnium carbide, hafnium nitride, titanium nitride, zirconium carbide or zirconium nitride. |
