Compositions Comprising Nickel-Titanium, Methods of Manufacture Thereof, and Articles Comprising the Same

NASA's Glenn Research Center has developed high-temperature solid lubricant materials suitable for foil gas bearings that enable the commercialization of a broad array of revolutionary oil-free gas turbines, compressors, blowers, motors, and other rotating machines that can operate from cryogenic to redhot temperatures. These tribological (friction and wear) coatings and composite powder metallurgy material innovations have immediate and proven spinoff potential for high-temperature steam turbine control valves, exhaust gas recirculation (EGR) valves, articulating ducts and piping joints, and other industrial and aerospace applications.
