Patent number: 6322746Abstract: Molded green parts are fused together to form a bond or joint during the sintering process. The molded green parts are held in intimate contact with each other and sintered at temperatures sufficient to fuse the parts together. The process may entail dry fusing of part-to-part or it may include the use of a flux between the parts being fused together to enhance the bond.Type: GrantFiled: June 13, 2000Date of Patent: November 27, 2001Assignee: Honeywell International, Inc.Inventors: Jerry C.

Patent number: 6261336Abstract: A composition for forming molded metal containing articles having improved stability. More particularly, a corrosion resistant composition for forming injection molded articles having a sodium silicate corrosion inhibiting additive. The corrosion inhibitor prevents metal oxidation when a metal containing powder is mixed with a water based binder, providing stability to the article and preventing generation of hydrogen gas. This significantly enhances the shelf life of the moldable composition prior to molding.Type: GrantFiled: August 1, 2000Date of Patent: July 17, 2001Assignee: Rutgers, The State University of New JerseyInventors: Mohammad Behi, Jerry C.

Patent number: H1193Abstract: This invention describes a process for producing copper alloys by rapid sdification in order to improve their strength and thermal stability after being exposed to elevated temperatures. The method used to rapidly solidify the molten alloy is either by use of a high pressure non-oxidizing gas spray to atomize the molten alloy into a powder or to pour the molten alloy onto a rotating wheel to form a ribbon which is then attrited into powder. The powder is canned, compacted to full density and cold worked to the desired shape.Type: GrantFiled: August 12, 1991Date of Patent: June 1, 1993Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Ravi Batra, Jerry C.
