New coating developed for Hubble is potential spin-off
NASA/GSFC NEWS RELEASE
Posted: June 13, 2000
Goddard's Hubble Project and Surmet Corporation in Burlington, Mass., put the diamond-hard coating, which the company calls UltraC Diamond(TM), through a rigorous test program to verify it could operate in the extremes of space. The coating covers tiny parts of an experimental cryogenic cooler, or "cryocooler," that will be attached onto Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) during a servicing mission in 2001. The cryocooler cools the detectors in the instrument and maintains them at 70 degrees Kelvin. This infrared instrument has been dormant since exhausting its supply of nitrogen ice in 1999. The cryocooler will restore NICMOS to full operation and extend its useful life.
"This new coating virtually eliminates wear and tear on moving parts," said Frank Cepollina, Manager of NASA's Hubble Space Telescope Development Project. "It has enormous potential for U.S. manufacturing -- especially in high tech, rotating machinery such as high speed turbines and pumps. The new coating also has many medical uses, such as in heart pumps and artificial hips and knees."
According to its manufacturer, UltraC Diamond(TM) can be deposited on a wide range of materials, including titanium (heart pump), ceramics, polymers, and prosthetics. The coating functions in a wide range of temperatures, from extremely low to moderately high. The UltraC Diamond(TM) coating is manufactured and applied at the Burlington, Mass. facilities of Surmet Corporation. A technology-based small business, Surmet specializes in developing and commercializing innovative coating technologies.
The next servicing mission is currently scheduled for next year.
