In Situ-Formed Debond Layer For Fibers

View page
US Patent:
6376074, Apr 23, 2002
Filed:
Mar 3, 2000
Appl. No.:
09/518926
Inventors:
Richard K. Everett - Alexandria VA
Alan S. Edelstein - Alexandria VA
John H. Perepezko - Madison WI
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
B32B 2520
US Classification:
428391, 4282934, 428364, 428375, 428378, 428396
Abstract:
A debonding layer is formed on fibers such as silicon carbide fibers by forming a thin film of a metal such as nickel or iron on the silicon carbide fibers and then annealing at a temperature of about 350-550Â C. to form a debond layer of a metal silicide and carbon. These fibers having the debond coating can be added to composite forming materials and the mixture treated to form a consolidated composite. A one heating-step method to form a consolidated composite involves inserting the silicon carbide fibers with just the initial metal film coating into the composite forming materials and then heating the mixture to form the debond coating in situ on the fibers and to form the consolidated composite. Preferred heating techniques include high temperature annealing, hot-pressing, or hot isostatic pressing (HIP).

Process For Preparing Aligned In-Situ Two Phase Single Crystal Composites Of Titanium-Niobium Alloys

US Patent:
6436208, Aug 20, 2002
Filed:
Apr 19, 2001
Appl. No.:
09/837900
Inventors:
Rabindra Mahapatra - Port Tobacco MD
Eui W. Lee - Maple Glen PA
Jeffrey Waldman - Huntington Valley PA
John H. Perepezko - Madison WI
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
C22C 1400
US Classification:
148562, 148404, 148421, 420418, 117 41
Abstract:
A process of preparing aligned, in-situ, two-phase single crystal alloys of titanium, aluminum and niobium which comprises growing the alloys at rates of about 3. 0 mm. to about 6. 0 mm. per hour by rotating a seed rod alloy consisting essentially of Ti-43 to 45 Al-10 to 12 Nb+0. 5 Si, in atomic percent, at about 7. 75 to 8. 25 RPM while in contact with a rotating feed rod alloy consisting essentially of Ti-43 to 45 Al-10 to 12 Nb, in atomic-percent, rotating at about 5. 75 to 6. 25 RPM in an atmosphere of substantially pure argon at melt temperatures ranging from about 1650Â C. to 1750Â C. to obtain two-phase single crystal alloys of Ti-43 to 45Al-10 to 12 Nb characterized as having improved ductility, excellent oxidation resistance, and high-temperature creep strength. These alloys are particularly useful for manufacturing high-temperature material components for internal combustion engines, gas turbines, and advanced aircraft engines.

428446, 428448, 428697, 428699, 428701, 428702, 428704
Abstract:
The invention provides oxidation resistant coatings for transition metal substrates and transition metal alloy substrates and method for producing the same. The coatings may be multilayered, multiphase coatings or gradient multiphase coatings. In some embodiments the transition metal alloys may be boron-containing molybdenum silicate-based binary and ternary alloys. The coatings are integrated into the substrates to provide durable coatings that stand up under extreme temperature conditions.
