99--TECHNOLOGY TRANSFER OPPORTUNITY THERMALLY ACTIVATED CRACK HEALINGMECHANISM FOR METALLIC MATERIALS: LAR-17681-1

Synopsis: NASA Langley Research Center in Hampton, VA solicits inquiries 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. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed an innovative coating to heal cracks in metal components, such as in aircraft and bridges. Currently the coating is used for in-laboratory repairs of surface cracks. Development continues with the ultimate goal of an in-situ healing mechanism that can work autonomously with structural health monitoring detectors. The metal structure is coated with a low-temperature healing agent and when a crack is produced under cyclic load it is then subjected to an external heat source (to heat the healing film to 250F - 300F). The component is processed in a vacuum. The coating has been prototyped on a titanium alloy sheet with an indium-tin eutectic alloy coating. Development is ongoing to produce a coating that does not require a vacuum and utilizes an integrated heat source. NASA is seeking to license this technology commercially. To express interest in this opportunity, please respond to [email protected] with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/ . These responses are provided to members of NASA Langleys Office of Strategic Analysis and Business Development OSACB for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
