  • Electrostatic varnish and precursor detection in lubricants
    Patent number: 10942161
    Abstract: Methods are provided for in-situ detection of varnish and/or deposit precursors in a lubricant in a lubricating environment. An electrostatic accumulator can be used within a lubricating environment to enhance accumulation of varnish and/or deposit precursors on portions of the electrostatic accumulator. The deposits accumulated on the electrostatic accumulator can then be characterized in-situ. The potential difference across portions of the electrostatic accumulator can cause an enhanced rate of deposit accumulation on the electrostatic accumulator, which can facilitate characterization of the tendency of a lubricant to accumulate deposits in the lubricating environment.

  • LUBRICANT COMPOSITIONS WITH IMPROVED PERFORMANCE AND METHODS OF PREPARING AND USING THE SAME
    Publication number: 20190136147
    Abstract: The present disclosure relates generally to lubricating compositions and methods of making and using the same. Specifically, the present disclosure relates to lubricating compositions and method of making and using the same for modifying friction at a metal-elastomer contact, and therefore improving at least one of elastomer lifetime, reducing elastomer wear, reducing metal wear, reducing energy consumption or a combination thereof. More specifically, one aspect of the present disclosure relates to lubricating compositions including at least two base oils with a viscosity difference between the first and second base oils; another aspect of the present disclosure relates to lubricating compositions comprising an additive that can modify friction at a metal-elastomer contact.
