  • 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.

  • Publication number: 20110046028
    Abstract: Provided are a mixed nano-lubricating oil and a method for preparing the same. The method for preparing a mixed nano-lubricating oil includes the steps of: (a) preparing a mixed solution by adding and mixing a nanopowder and a dispersant to a solvent and pulverizing the nanopowder to a primary particle level; (b) modifying the surface of the nanopowder; (c) substituting the solvent of the mixed solution to a lubricating oil; and (d) mixing at least two nano-lubricating oils prepared using physically and chemically different nanopowders. According to the present invention, it is possible to improve the wear resistance and the load resistance at the same time by mixing at least two kinds of lubricating oils having excellent wear resistance or load resistance.
