Patent number: 9315757Abstract: The present application is directed to methods and devices for altering material properties of lubricants and other cross-linkable compounds comprising organic or organometallic materials through exposure to energized gaseous species. The energized gaseous species may create reactive sites among lubricant molecules that may alter their material properties by cross-linking at least a portion of the lubricant molecules. The cross-linked lubricant may reduce the ability of the lubricant to migrate away when force is applied between lubricated sliding friction surfaces.Type: GrantFiled: August 20, 2015Date of Patent: April 19, 2016Assignee: TriboFilm Research, Inc.Inventors: Jackson Thornton, Vinay G.

Patent number: 8084103Abstract: One embodiment comprises a method for increasing the hydrophobic characteristics of a surface. A coupling agent is applied to the surface, and the surface is subsequently exposed to a first ionizing gas plasma at about atmospheric pressure for a predetermined period of time. The ionizing gas plasma may be formed from a mixture of a carrier gas and a reactive gas. The reactive gas may be comprised of one or more hydrocarbon compound such as an alkane, an alkene, and an alkyne. Alternatively, the reactive gas may be a fluorocarbon or organometallic compound. A lubricant may then be applied to the surface, followed by exposure to second ionizing gas plasma.Type: GrantFiled: January 16, 2009Date of Patent: December 27, 2011Inventors: Vinay G.

Publication number: 20080041272Abstract: A gradient coating is comprised of a basecoat derived from a polysiloxane prepolymer obtained from a mixture of one to three alkoxysilane monomers and at least one diepoxide monomer, and a lubricious reactant. The basecoat is applied to a substrate and dried. The lubricious reactant is then applied and allowed to permeate into the basecoat. The basecoat and lubricious reactant are then co-cured, resulting in a gradient coating composition. In addition to providing enhanced scratch and mar resistance, the gradient coating composition is solvent resistant and provides a durable hydrophobic and oleophobic surface, which makes it useful as a corrosion protectant and as a release agent.Type: ApplicationFiled: July 24, 2007Publication date: February 21, 2008Inventors: Charles Tomasino, Charles Chiklis, Vinay Sakhrani

An inner electrode may fit at least partially within the workpiece so as to create a plasma discharge zone between the inner electrode and an inner surface of the workpiece. A gas supply manifold may be included that directs a gas into the plasma discharge zone. A power supply may be used to generate an ionizing gas plasma in the plasma discharge zone. In one embodiment, there is a coating on an inner surface of the workpiece.Type: ApplicationFiled: April 3, 2007Publication date: October 11, 2007Inventors: Vinay G. Sakhrani, Charles Tomasino
