Resilient and Corrosion-Proof Rolling Element Bearings Made from Superelastic Ni-Ti Alloys for Mechanical Applications


Mechanical components (bearings, gears, mechanisms) typically utilize hardened construction materials to minimize wear and attain long life. In such components, loaded contact points (e.g., meshing gear teeth, bearing balls-raceway contacts) experience high contact stresses. The combination of high hardness and high elastic modulus often leads to damaging contact stress and denting, particularly during transient overload events such as shock impacts that occur during the launching of space vehicles or the landing of aircraft.

In this webinar, Dr. DellaCorte will introduce the results of a NASA Glenn research project that employs a superelastic alloy, Ni-Ti for rolling element bearing applications. Bearings and components made from such alloys can alleviate many problems encountered in advanced aerospace applications and may solve many terrestrial applications as well.

altAlso, Kim Dalgleish-Miller, Chief of the NASA Glenn Research Center’s Innovation Projects Office, will discuss the exciting technologies being developed at Glenn for NASA missions. The Glenn Research Center excels in researching and developing innovative technologies for both aeronautics and space flight that revolutionize air travel and enable further exploration of the universe. Glenn’s expertise includes high-temperature materials and composites, communications, electronics and sensors, as well as energy and propulsion.
