Patent number: 10689745Abstract: A process of converting an outer layer of an object made of a refractory metal, such as titanium, into a carbide of the refractory metal. A molten metal, such as molten lithium, is placed adjacent the outer surface of the object. The lithium does not react with the titanium, nor is it soluble within the titanium to any significant extent at the temperatures involved. The molten lithium contains elemental carbon, that is, free carbon atoms. At high temperature, the carbon diffuses into the titanium, and reacts with titanium atoms to form titanium carbide in an outer layer. Significantly, no other atoms are present, such as hydrogen or oxygen, which can cause problems, because they are blocked by the molten lithium.Type: GrantFiled: February 8, 2017Date of Patent: June 23, 2020Assignee: IAP Research, Inc.Inventors: Julius John Bonini, Bhanumathi Chelluri, Edward Arlen Knoth

Patent number: 7758784Abstract: A method of uniformly dispersing a nano powder throughout a micron powder. Ordinary mixing or agitation does not succeed in attaining uniform dispersal: the nano powder agglomerates into microscopic masses. In one form of the invention, a charge of a micron powder, with fifty weight percent of charge of nanopowder is loaded into a ball mill. The mixture is ball milled for less than two hours, at room temperature in a dry condition, and produces a highly uniform distribution of the nano powder throughout the micron powder.Type: GrantFiled: September 14, 2006Date of Patent: July 20, 2010Assignee: IAP Research, Inc.Inventors: Bhanumathi Chelluri, Edward Arlen Knoth, Edward John Schumaker, Ryan D.

Patent number: 7361301Abstract: This invention relates to a system and method for consolidating particulate material, such as particulate material, in order to achieve at least ninety-five percent (95%) or even ninety-eight percent (98%) of its maximum theoretical density using a relatively long duration, relatively low current density current flow through the material. In one embodiment, the consolidation system includes a feedback control for monitoring various characteristics associated with the particulate material being consolidated and providing feedback information to a power supply which controls the amount of current supplied to the particulate material in order to achieve the desired density. The consolidation system and method is characterized in that the duration of the current is greater than 0.1 second, but typically less than about 1 second, while the current is less than about 10 KA/cm2.Type: GrantFiled: September 2, 2003Date of Patent: April 22, 2008Assignee: IAP Research, Inc.Inventors: David P.

Patent number: 7362015Abstract: This invention relates to a transformer and more particularly, to a system and method for making a transformer utilizing dynamic magnetic compaction. A coil is placed in a conductive container, and a conductive powder material, such as ferrite, is placed in the container and surrounds the coil and the turns of the coil. A power supply energizes a capacitor which subsequently provides a high energizing current to a second, energizing coil within which the container, material and inner coil are situated, thereby causing the container, powder materials and coil to be compacted to provide an electrical component, such as a transformer, motor, commutator, rotor or choke.Type: GrantFiled: September 13, 2004Date of Patent: April 22, 2008Assignee: IAP Research, Inc.Inventors: John P Barber, David P Bauer, Edward K Knoth, Duane C Newman

Patent number: 6524526Abstract: Structure and method for producing very dense bodies of material from particulate materials. A particle material is placed within an electrically conductive container. A solenoid or coil encompasses the electrically conductive container, and a large magnitude of electrical current is caused to flow through the solenoid or coil. As the electrical current flows through the solenoid or coil, large magnitudes of magnetic pressures are created upon the electrically conductive container, and the electrically conductive container is compressed, and the transverse dimension thereof is reduced. Thus, the particulate material within the electrically conductive container is firmly compacted, and a rigid body of material is provided. Any one of numerous types of particulate material may be employed. A method and system for selecting various parameters which enable the material to be densified to densities in excess of 90% of the material's maximum density is also illustrated in another embodiment of the invention.Type: GrantFiled: August 1, 2001Date of Patent: February 25, 2003Assignee: IAP Research, Inc.Inventor: John P.
