- Description
- Pacific Northwest National Laboratory (PNNL), operated by Battelle Memorial Institute under contract to the U.S. Department of Energy, solicits interest from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. PNNL may also be available to licensee(s) to assist in further research and development of the technology under a sponsored research agreement or CRADA program. THE TECHNOLOGY: Tough, high-strength joints between SiC and SiC have been fabricated using displacement reactions between Si and Mo or Ti metal carbides. The joints exhibit high-strength bonding to SiC and possess a desirable composite microstructure in the joint region due to the displacement reaction occurring between the Si and metal carbide. This microstructure gives the joint region high strength and fracture toughness. The formation of SiC during the displacement reaction facilitates the formation of the strong bond between the joint and the SiC. The reaction products are SiC and metal silicides or metal carbo-silicides. Joints have been made at temperatures above and below the melting point of Si (1410 C) so that either solid state or liquid-phase displacement reactions can be used. Joints can be processed using blended powder compacts that are cold-pressed and then hot-pressed or can take advantage of tape calendaring techniques to make a precursor layered tape that can be subsequently hot-pressed to form the joint. For joining SiC to SiC there is no need for a graded joint region, but for joining dissimilar materials, a graded joint can be made using these techniques. This is especially suited to the tape calendaring technique. The formation of a graded joint can be accomplished by varying the relative amounts of starting reactants for the subsequent displacement reaction to promote the formation of both a microstructure and phase equilibria that varies throughout the thickness of the joint. Obvious extensions of this technology are the fabrication of tough coatings for SiC or other materials. and making joints between SiC-based composites. US Pat No 6,165,301, and 6,277,493. NOTE: THIS IS NOT A PROCUREMENT. Any company interested in licensing this technology must respond with a letter of interest (may be submitted by e-mail) no later than 90 days from the publication date of this Notice summarizing the company?s business and technical expertise and motivation for pursuing this opportunity. Companies deemed appropriate will be provided with further information on the technology. Such information may require an executed Nondisclosure Agreement. Respondents wishing to enter into negotiations for a commercial license will be required to submit a business plan for the commercialization of the technology prior to licensee(s) selection and negotiations. Please send letters of interest to the attention of the POC identified within this Notice.
