Deposition Of Materials With Low Ductility Using Solid Free-Form Fabrication
US Patent:
2010019, Aug 5, 2010
Filed:
Jan 30, 2009
Appl. No.:
12/362722
Inventors:
Robbie Joseph Adams - Phoenix AZ, US
Assignee:
HONEYWELL INTERNATIONAL INC. - Morristown NJ
International Classification:
B23K 15/00, B23K 9/00
US Classification:
21912115, 21912147
Abstract:
A solid free-form (SFF) method is used to manufacture a component from successive layers of feedstock material with low ductility. A plasma stream is created by energizing a flowing gas using an arc electrode, the arc electrode having a variable magnitude current supplied thereto. The plasma stream is directed to a predetermined targeted region to preheat the predetermined targeted region prior to deposition. The current is adjusted and the feedstock material is introduced into the plasma stream to deposit molten feedstock in the predetermined targeted region. The current is adjusted and the molten feedstock is slowly cooled at an elevated temperature, typically above the brittle to ductile transition temperature of the feedstock material, in a cooling phase to minimize the occurrence of material stresses.

US Patent:
6946096, Sep 20, 2005

Appl. No.:
10/439637
Inventors:

Assignee:
Honeywell International, Inc. - Morristown NJ
International Classification:
B22F003/14, B22F005/00
US Classification:
419 10, 419 14, 419 19, 419 26, 419 48
Abstract:
A method for making aerospace face seal rotors reinforced by rhenium metal, alloy, or composite in combination with silicon carbide or other ceramic. The resulting rotor also is disclosed. Ceramic grains, preferably silicon carbide (SiC), are mixed with powdered metallic (PM) binder that may be based on a refractory metal, preferably rhenium. The mixture is applied to a rotor substrate. The combined ceramic-metal powder mixture is heated to sintering temperature under pressure to enable fusion of the ceramic in the resulting metal-based substrate. A load may then be applied under an elevated temperature. The resulting coated rotor can exhibit high hot hardness, increased durability and/or high hot wear resistance, as well as high thermal conductivity.

International Classification:
B23K 10/00
US Classification:
21912136, 21912147, 219 7616, 427446
Abstract:
A solid free form fabrication (SFF) system and method is used to fabricate a three-dimensional structure in a continuous manner from successive layers of feedstock material. The system includes a gas shielding structure that is configured to protect a targeted region from oxidation. The system further includes a positioning arm coupled to the deposition head and moveable to align the deposition head with a targeted region of the three-dimensional structure and a plurality of control components coupled to the positioning arm for controlling a position of the positioning arm and operation of the deposition head. The gas shielding structure is formed as either a parallelepiped structure or a half disc structure and may be conformable to at least one surface of the three-dimensional structure.
Flywheel Secondary Bearing With Rhenium Or Rhenium Alloy Coating
US Patent:
6987339, Jan 17, 2006
Filed:

Assignee:
Honeywell International, Inc. - Morristown NJ
International Classification:
H02K 7/09
US Classification:
310 905
Abstract:
A bearing for a high-speed and high-momentum rotating flywheel system for satellite or other applications that enables better recovery when unintended physical contact occurs. This better recovery is achieved through increased impact resistance and wear resistance by using a flat annulus connected to the main shaft of the primary bearing and secondary metal bearing and coating both annuli with rhenium or its alloys. Rhenium has a very high melting point but in the annealed condition is ductile so the rhenium coating is hardened to a very high strength and wear resistance but the rhenium beneath is still ductile. This combination of hard and soft material provides good wear resistance and impact resistance for those times when the primary bearing ceases to operate and contact is made with the secondary bearing.
Ion Fusion Formation Process For Large Scale Three-Dimensional Fabrication
US Patent:
2009002, Jan 29, 2009
Filed:
Jul 26, 2007
Appl. No.:
11/828819
Inventors:
Robbie J. Adams - Phoenix AZ, US
Assignee:
HONEYWELL INTERNATIONAL, INC. - Morristown NJ
International Classification:
B23K 10/00, B05D 1/08, B23K 9/04
US Classification:
219 7616, 219 761, 427446
Abstract:
An ion fusion formation (IFF) system and method is used to fabricate a large scale three-dimensional structure in a continuous manner from successive layers of feedstock material. The system includes a moveable positioning arm coupled to a control platform. The positioning arm includes a deposition head, including a high energy beam and a feedstock feed mechanism mounted thereto. The deposition head is positioned relative to a targeted region by positioning and repositioning the moveable positioning arm, thereby providing a means for fabricating a large scale three-dimensional structure in a continuous manner. A plurality of control components coupled to the control platform are programmable to control the positioning arm whereby a plurality of customizable control parameters are input into the control components and provide positioning and repositioning of the positioning arm to align the deposition head relative to the predetermined targeted region.
