Puris LLC, Bruceton Mills, W. Va., recently signed a limited (partially) exclusive, term license agreement with NASA’s Glenn Research Center, Cleveland to produce a high-performance alloy enhanced with hafnium 60NiTi(Hf) that will be marketed under the brand name SM-103TM.
Lotus-leaf inspired coating
A new class of superhydrophobic materials mimics one of the planet’s most water-repelling surfaces: the lotus leaf. The material is inexpensive, nontoxic, and can be applied to a variety of surfaces via spray- or spin-coating. The hydrocarbon-based material may be a “green” replacement for costly, hazardous fluorocarbons commonly used for superhydrophobic applications, says Andrew Barron, […]
Enhancing energy-efficiency with novel coating technology
A research effort led by the University of Colorado Boulder to develop an inexpensive, “do-it-yourself” coating to retrofit energy-inefficient windows in residential and commercial buildings has been given a $4 million boost over three years by the U.S. Department of Energy.
Rapid Plasma Deposition machine can 3D-print 22 tons of titanium parts per year
Norsk Titanium AS, Norway, demonstrated its fourth-generation Rapid Plasma Deposition machine by producing a unique structural titanium spar for one of the world’s largest commercial aircraft manufacturers at its Technology Centre in Oslo.
Spray Tips: Detonation Gun
In detonation gun spraying, an explosive mixture of fuel, oxygen, and powder is introduced into a long tube/barrel and is ignited by a spark plug. The resulting detonation-pressure wave heats and accelerates the entrained powder particles, which travel down the water-cooled barrel toward the substrate. Nitrogen is used to purge the barrel between detonations.
