  • Lubricant additives, lubricant compositions, and applications of same
    Patent number: 10745637
    Abstract: A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each molecule includes a surface active group attractable to a target surface, wherein the surface active group comprises a carboxyl group, a siloxyl group, an amine group, or a mixture thereof, and a carbon containing component connected to the surface active group, wherein the carbon containing component comprises a carbon ring, wherein the surface active group and the carbon containing component are adapted such that the carbon film is formed in situ on the target surface of the target machine only when tribological energy activates the lubricant additive to unravel the carbon containing component under a pressure and a temperature during operation.
    Type: Grant
    Filed: July 25, 2019
    Date of Patent: August 18, 2020
    Assignee: NORTHWESTERN UNIVERSITY
    Inventors: Yip-Wah Chung, Qian Wang, Blake A. Johnson

  • Lubricant additives, lubricant compositions, and applications of same
    Patent number: 10414997
    Abstract: A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each lubricant additive molecule includes a surface active group attractable to a target surface, and a carbon containing component connected to the surface active group, for providing a carbon source to form a carbon film on the target surface. A method for in situ forming of a carbon film using the lubricant composition, includes adding the lubricant composition into a target machine such that the lubricant composition is in contact with a target surface of the target machine, and operating the target machine to cause a temperature and a pressure at the target surface so that the carbon containing component is unraveled thereon to form a carbon film on the target surface during the operation.
