  • Robust superlubricity with steel surfaces in sliding contacts
    Patent number: 12173245
    Abstract: A low friction wear surface with a coefficient of friction in the superlubric regime under a sliding and rolling movement. The low friction wear surface includes molybdenum disulfide and graphene oxide on a first wear surface with a tribolayer formed on a rough steel counter surface during the sliding and rolling movement. Methods of producing the low friction wear surface are also provided.
    Type: Grant
    Filed: June 18, 2021
    Date of Patent: December 24, 2024
    Assignee: UChicago Argonne, LLC

  • Low friction coatings
    Patent number: 11440049
    Abstract: A low friction, wear-resistant surface operable at high temperatures and high loads with a low coefficient of friction including boron nitride and graphene-oxide on steel or nanodiamonds and graphene on aluminum. The low friction, wear-resistant surface remains with a coefficient of friction in the superlubric regime at temperatures in between about 200° C. and 970° C.
