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. Sakhrani, Charles Tomasino, Robert A. Mineo

Patent number: 7553529Abstract: A method for preparing one or more lubricated surfaces of an article to reduce the break-out force and sliding frictional force. A lubricant is applied to one or more surfaces, and the lubricant-coated surface is treated by exposing the surface to an energy source, wherein the energy source is an ionizing gas plasma at about atmospheric pressure, gamma radiation, or electron beam radiation. One or more of the surfaces may be exposed to the ionizing gas plasma at about atmospheric pressure prior to application of the lubricant. Another aspect of the invention is articles produced using one or more methods of the invention.Type: GrantFiled: June 13, 2008Date of Patent: June 30, 2009Assignee: TriboFilm Research, Inc.Inventors: Vinay G. Sakhrani, Joel L. Williams, Charles Tomasino, Paul M. Vernon

Publication number: 20090126404Abstract: 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: ApplicationFiled: January 16, 2009Publication date: May 21, 2009Applicant: TriboFilm Research, Inc.Inventors: Vinay G. Sakhrani, Charles Tomasino

Publication number: 20090103074Abstract: The present application is directed to methods for performing quality control analysis of a process to treat a surface of a workpiece. A sensor is placed in proximity to the surface, and a controller analyzes data obtained by analyzing a signal from the sensor. The controller may determine whether the process started properly, the presence of a lubricant on the surface, and the amount of the lubricant.Type: ApplicationFiled: October 17, 2007Publication date: April 23, 2009Applicant: TRIBOFILM RESEARCH, INC.Inventors: Jerome J. Cuomo, Vinay G. Sakhrani

Patent number: 7264669Abstract: 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: GrantFiled: February 3, 2005Date of Patent: September 4, 2007Assignee: Tribofilm Research, Inc.Inventors: Charles Tomasino, Charles K.
