Patent number: 8728993Abstract: A PTFE-based composite material includes a PTFE major phase filled with a metal oxide minor phase. The major phase is intermixed with the metal oxide minor phase, wherein the minor phase includes a plurality of irregularly shaped metal oxide nanoparticles. The irregularly shaped nanoparticles provide substantial reductions in steady state wear rate over otherwise similar nanocomposites. The metal oxide can comprise aluminum oxide.Type: GrantFiled: January 11, 2013Date of Patent: May 20, 2014Assignee: University of Florida Research Foundation, Inc.Inventors: W. Gregory Sawyer, David L. Burris

Patent number: 7960317Abstract: A method for in-situ solid lubrication of sliding electrical contacts includes the steps of providing a device having a movable electrically conductive first member and an electrically conductive second member, the first and second member being in electrical contact at a slideable electrical contact, and automatically applying an electrically conductive solid lubricant transfer film to the slideable electrical contact during operation of the device. The applying step can be a deposition of the electrically conductive solid lubricant transfer film on a surface of the first member, wherein the electrically conductive solid lubricant transfer film is carried by movement of the first member to the electrical contact.Type: GrantFiled: March 8, 2006Date of Patent: June 14, 2011Assignee: University of Florida Research Foundation, Inc.Inventors: John C.
