  • Synthesis of oil containing microcapsules and their use in functional composite coatings
    Patent number: 8771494
    Abstract: Systems and methods for the synthesis of lubricant-containing microcapsules are disclosed. Embodiments of composite nickel and copper coatings containing capsules with liquid lubricating oil cores are also disclosed. In certain embodiments, microcapsules can be incorporated into a metal plating solution to perform composite electrodeposition to obtain self lubricant metallic coatings. In some embodiments, much lower friction coefficient (˜0.8) and far better wear resistance was obtained with the copper/microcapsules composite.
    Type: Grant

  • Method for electrochemical plating and marking of metals
    Patent number: 8257572
    Abstract: A method for the electrochemical plating or marking of metals includes providing a metal surface, providing an electroplating solution at the metal surface, and electroplating the metal surface with the electroplating solution. A top layer of the metal surface comprises an oxide scale. The method can also include masking a portion of the metal surface with a masking material. The electroplating solution can be provided at the metal surface by an electroplating brush, the oxide scale of the metal surface can be comprised primarily of magnetite and hematite, and the material comprising the metal surface can be steel.
