Elaine Soltani has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and electrolyte compositions for electrodepositing metal-carbon alloys
    Patent number: 5759243
    Abstract: Methods for electrodepositing a metal-carbon coating on a substrate comprng immersing the substrate in an aqueous electrolyte, and passing a sufficient current through the electrolyte to effect electrolyte deposition of a metal-carbon alloy on the substrate. The aqueous electrolyte comprises from about 0.2 to about 0.6 mol/l of metal ions selected from the group consisting of iron, nickel, nickel-tungsten mixture and cobalt-tungsten mixture, greater than about 1.4 mol/l of an amidosulfonic acid or a salt thereof, ammonium ions, formic acid or a salt thereof, and water.
    Type: Grant
    Filed: June 2, 1997
    Date of Patent: June 2, 1998
    Assignee: The United States of America as represented by the Secretary of Commerce
    Inventors: Christian E. Johnson, David Lashmore, Elaine Soltani

  • Methods and electrolyte compositions for electrodepositing chromium coatings
    Patent number: 5415763
    Abstract: Methods for electrodepositing a chromium coating on a substrate comprising mmersing the substrate in an aqueous electrolyte, and passing a sufficient current through the electrolyte to effect deposition of a chromium coating on the substrate. The aqueous electrolytes comprise from about 0.2 to about 0.6 mol/l of trivalent chromium ions, greater than about 1.4 mol/l of an amidosulfonic acid or a salt thereof, ammonium ions, formic acid or a salt thereof, and water.
