Publication number: 20230272226Abstract: Articles including durable and icephobic and/or biocidal polymeric coatings are disclosed. The polymeric coatings can include a bonding layer which may contain a substantially fully cured polymeric resin providing excellent adhesion to metallic or polymer substrates. The polymeric coating further includes an outer surface layer which is smooth, hydrophobic, biocidal and icephobic and, in addition to a substantially fully cured resin, contains silicone comprising additives near the exposed outer surface. The anisotropic polymeric coatings are particularly suited for strong and lightweight parts required in aerospace, automotive and sporting goods applications. A process for making the articles is disclosed as well.Type: ApplicationFiled: April 12, 2023Publication date: August 31, 2023Inventors: GINO PALUMBO, HERATH KATUGAHA, JONATHAN MCCREA, KLAUS TOMANTSCHGER, KONSTANTINOS PANAGIOTOPOULOS

Publication number: 20230184120Abstract: Sacrificial inserts for use in gas turbine engines to reduce friction and wear damage between compressor fan blades and the fan rotors are disclosed. The consumable metallic shims have low friction and reduce fretting and galling on fan blade roots and fan rotor dovetail slots thereby increasing their operating lives, as well as reduce engine noise and improve engine efficiency. The electroformed, compliant, multi-purpose shims may have variable thickness and, when positioned between the blade dovetail root and the rotor disk dovetail slot, prevent movement and slippage between air foil blades and the rotor.Type: ApplicationFiled: January 26, 2023Publication date: June 15, 2023Inventors: Jonathan McCrea, Gino Palumbo, Klaus Tomantschger, David Lionel Limoges

Patent number: 9970120Abstract: A method for electrodepositing a coating/free-standing layer on a workpiece in an electrolytic cell includes moving the workpiece and an anode applicator tool having a consumable anode insert relative to each other; anodically dissolving a metal from the insert and cathodically depositing the metal on the workpiece; providing flow of electrolyte solution through the insert to ensure that greater than 90% of the anodic reaction is represented by dissolution of the metal; recirculating collected electrolyte solution exiting the electrolytic cell through the insert; applying an electric current to the electrolytic cell; maintaining a concentration of the anodically dissolved metal within ±25% of each Ampere-hour per liter of electroplating solution; and creating a cathodic electrodeposit on the workpiece which includes the anodically dissolved metal, the chemical composition of the deposit varying by less than 25% in the deposition direction over a selected thickness of up to 25 microns of the deposit.Type: GrantFiled: January 18, 2016Date of Patent: May 15, 2018Assignee: Integran Technologies Inc.Inventors: Klaus Tomantschger, Diana Facchini, Francisco Gonzalez, Jonathan McCrea, John Kratochwil, Dan Woloshyn, Yusuf Bismilla, Nandakumar Nagarajan, Mioara Neacsu

Patent number: 9249521Abstract: Anode applicators include consumable anodes, that can be operated in a non-stationary mode and are insensitive to orientation, are used in selective plating/brush electrodeposition of coatings or free-standing components. The flow-through dimensionally-stable, consumable anodes employed are perforated/porous to provide relatively unimpeded electrolyte flow and operate at low enough electrochemical potentials to provide for anodic metal/alloy dissolution avoiding undesired anodic reactions. The consumable anodes include consumable anode material(s) in high surface area to reduce the local anodic current density. During electroplating, sufficient electrolyte is pumped through the consumable anodes at sufficient flow rates to minimize concentration gradient and/or avoid the generation of chlorine and/or oxygen gas and/or undesired reaction such as the anodic oxidation of P-bearing ions in the electrolyte.Type: GrantFiled: November 4, 2011Date of Patent: February 2, 2016Assignee: Integran Technologies Inc.Inventors: Klaus Tomantschger, Diana Facchini, Francisco Gonzalez, Jonathan McCrea, John Kratochwil, Dan Woloshyn, Yusuf Bismilla, Nandakumar Nagarajan, Mioara Neacsu

Patent number: 9005420Abstract: Variable property deposit, at least partially of fine-grained metallic material, optionally containing solid particulates dispersed therein, is disclosed. The electrodeposition conditions in a single plating cell are suitably adjusted to once or repeatedly vary at least one property in the deposit direction. In one embodiment denoted multidimension grading, property variation along the length and/or width of the deposit is also provided. Variable property metallic material deposits containing at least in part a fine-grained microstructure and variable property in the deposit direction and optionally multidimensionally, provide superior overall mechanical properties compared to monolithic fine-grained (average grain size: 2 nm-5 micron), entirely coarse-grained (average grain size: >20 micron) or entirely amorphous metallic material deposits.Type: GrantFiled: December 20, 2007Date of Patent: April 14, 2015Assignee: Integran Technologies Inc.Inventors: Klaus Tomantschger, Glenn Hibbard, Gino Palumbo, Iain Brooks, Jonathan McCrea, Fred Smith

Patent number: 8916248Abstract: Metal-coated polymer articles containing structural substantially porosity-free, fine-grained and/or amorphous metallic coatings/layers optionally containing solid particulates dispersed therein on polymer substrates, are disclosed. The substantially porosity-free metallic coatings/layers/patches are applied to polymer or polymer composite substrates to provide, enhance or restore vacuum/pressure integrity and fluid sealing functions. Due to the excellent adhesion between the metallic coating and the polymer article satisfactory thermal cycling performance is achieved. The fine-grained and/or amorphous metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, aerospace and automotive parts and other components exposed to thermal cycling and stress created by erosion and impact damage.Type: GrantFiled: February 1, 2013Date of Patent: December 23, 2014Assignee: Integran Technologies, Inc.Inventors: Jonathan McCrea, Francisco Gonzalez, Gino Palumbo, Klaus Tomantschger, Rich Emrich, Konstantinos Panagiotopoulos, Mary Pasquantonio, John Kratochwil, Herath Katugaha
