  • Patent number: 9243204
    Abstract: A wear resistant lubricious composite includes a synthetic resin binder, a plurality of transfer film forming particles, and a plurality of hard nanoparticles. The hard nanoparticles are selected from the group consisting of metal oxides, metal carbides and metal nitride nanoparticles. A method of forming wear resistant lubricious composite articles includes the steps of providing a liquid phase synthetic resin precursor, adding a plurality of transfer film forming particles and a plurality of hard nanoparticles selected from the group consisting of metal oxide, metal carbide and metal nitride nanoparticles to the resin precursor to form a mixture, adding a hardener to the mixture, and curing the mixture.
    Type: Grant
    Filed: October 10, 2014
    Date of Patent: January 26, 2016
    Assignee: University of Florida Research Foundation, Inc.

  • Patent number: 8728993
    Abstract: 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.

  • Patent number: 7960317
    Abstract: 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.
