Publication number: 20200080199Abstract: A method and apparatus for producing a corrosion inhibiting coating for metal and metal alloy substrates. The coating is comprised of a metal or metal alloy that is similar in composition to the substrate to be coated, further combined with a corrosion inhibiting material. The corrosion inhibiting material may be a refractory metal or metalloid. The method and apparatus for producing the coating allows for the corrosion inhibiting coating to have a supersaturated concentration of the corrosion inhibiting material alloyed with another metal or metal alloy. The method and apparatus allow for the selective vaporization of material sources to make the coating vapor, which are then entrained in a high speed gas flow that directs the coating vapor onto the substrate. Optional plasma assistance and application of a voltage to the substrate may be used. The coating may be customized for a variety of applications.Type: ApplicationFiled: February 20, 2018Publication date: March 12, 2020Applicants: University of Virginia Patent Foundation, THE GOVERNMENT OF THE UNITED STATES, AS RESPRESENTED BY THE SECRETARY OF THE NAVYInventors: Haydn N. G. Wadley, Arthur H. Heuer, Paul Natishan

Patent number: 6610361Abstract: Multi-layer assemblies of polysilicon thin films having predetermined stress characteristics and techniques for forming such assemblies are disclosed. In particular, a multi-layer assembly of polysilicon thin films may be produced that has a stress level of zero, or substantially so. The multi-layer assemblies comprise at least one constituent thin film having a tensile stress and at least one constituent thin film having a compressive stress. The thin films forming the multi-layer assemblies may be disposed immediately adjacent to one another without the use of intermediate layers between the thin films. Multi-layer assemblies exhibiting selectively determinable overall bending moments are also disclosed. Selective production of overall bending moments in microstructures enables manufacture of such structures with a wide array of geometrical configurations.Type: GrantFiled: November 26, 1999Date of Patent: August 26, 2003Assignee: Case Western Reserve UniversityInventors: Arthur H. Heuer, Harold Kahn, Jie Yang, Stephen M. Phillips

Patent number: 6024003Abstract: An apparatus for forming an integral three-dimensional object from a plurality of individual laminations includes a cutting surface on which each of the laminations is individually deposited. A concentrated energy source cuts each of the plurality of laminations into a shape required for assembly of the laminations into the integral three-dimensional object. A transfer mechanism removes each of the cut laminations from the cutting surface and stacks each of the cut laminations on an assembly surface. The transfer mechanism includes a gripper face having a peripheral portion and a central portion. A mask is positioned on the gripper face. The mask has an apertured central portion corresponding to the cut lamination. A source of suction communicates with the gripper face and a valve mechanism selectively draws a suction on the gripper face peripheral portion, the gripper face central portion, both or neither.Type: GrantFiled: August 19, 1998Date of Patent: February 15, 2000Assignee: Case Western Reserve UniversityInventors: Wyatt S. Newman, James D. Cawley, Arthur H. Heuer

Patent number: 5779833Abstract: A method for manufacturing an integral three dimensional object from laminations includes the steps of fabricating a plurality of first sheets of a first material composition, cutting each of the first sheets to form a contoured layer representing a cross-section of the three dimensional object and to form a waste material and discarding the waste material. The contoured layers are stacked in a desired sequence to form a stack of contoured layers which are then laminated. Subsequently, the contoured layers of the stack are secured to each other to form the integral three dimensional object. This method works particularly well with ceramic material sheets. If desired, a second type of sheet made of a fugitive material can also be cut to form a contoured layer representing a void in a cross-section of the three dimensional object. The contoured layers of the second sheets are then stacked along with the contoured layers of the first sheets to form the object.Type: GrantFiled: April 12, 1996Date of Patent: July 14, 1998Assignee: Case Western Reserve UniversityInventors: James D.
