Patent number: 10196929Abstract: A system and methods for applying a ceramic coating to a component that includes first applying a coating material to a first portion of a component. A removal agent is then applied to a second portion of the component that has an overspray byproduct thereon, and then the ceramic coating material is applied to at least the second portion of the component.Type: GrantFiled: February 20, 2013Date of Patent: February 5, 2019Assignee: General Electric CompanyInventors: Thomas Edward Mantkowski, Raymond William Heidorn, Nripendra Nath Das, Anthony Wayne Reynolds

Patent number: 7216485Abstract: A method for adjusting the airflow in a turbine component having a plurality of airflow holes. The method comprises the step of depositing an overlay metallic coating on the surface of the turbine component in a manner such that at least some of the airflow holes are partially filled such that the volume of the partially filled airflow holes is changed so as to adjust the airflow through the turbine component. Also provided is a turbine component having a plurality of airflow holes, at least some of the airflow holes being partially filled with the overlay metallic coating to change the volume thereof so as to adjust the airflow through the turbine component.Type: GrantFiled: September 3, 2004Date of Patent: May 15, 2007Assignee: General Electric CompanyInventors: James Michael Caldwell, Thomas John Tomlinson, Robert George Zimmerman, Jr., Raymond William Heidorn, Gilbert Farmer

Patent number: 7094450Abstract: A method applying a thermal barrier coating to a metal substrate, or for repairing a thermal barrier coating previously applied by physical vapor deposition to an underlying aluminide diffusion coating that overlays the metal substrate. The aluminide diffusion coating is treated to make it more receptive to adherence of a plasma spray-applied overlay alloy bond coat layer. An overlay alloy bond coat material is then plasma sprayed on the treated aluminide diffusion coating to form an overlay alloy bond coat layer. A ceramic thermal barrier coating material is plasma sprayed on the overlay alloy bond coat layer to form the thermal barrier coating. In the repair embodiment of this method, the physical vapor deposition-applied thermal barrier coating is initially removed from the underlying aluminide diffusion coating.Type: GrantFiled: April 30, 2003Date of Patent: August 22, 2006Assignee: General Electric CompanyInventors: Bangalore Aswatha Nagaraj, Eva Zielonka Lanman, Deborah Anne Schorr, Thomas John Tomlinson, Raymond William Heidorn, David Allen Kastrup, Craig Douglas Young

Patent number: 6993811Abstract: A method for applying diffusion aluminide coating on a selective area of a turbine engine component and the coating produced by that method is disclosed. A quartz infrared lamp heats only substantially the localized area of the component to be coated, rather than the complete part. Either halide activated or non-activated tape is applied on the area to be coated and is held in place during coating using a high temperature dimensionally stable tape holder manufactured from graphite or ceramic. The quartz infrared lamp is used to heat only the desired area to a coating temperature of about 1800° F. to about 2000° F. under an inert atmosphere for about 3 to about 8 hours to achieve the desired aluminide coating thickness. No powder masking of the machined surface area is required. Due to the localized heating, aluminum vapor generated from the tape will only deposit aluminide coating on the taped area.Type: GrantFiled: October 17, 2002Date of Patent: February 7, 2006Assignee: General Electric CompanyInventors: Nripendra Nath Das, Raymond William Heidorn, Walter Michael Gmerek, Jr., David Andrew Jablonka

Patent number: 6821564Abstract: Apparatus and method to improve vapor phase diffusion coating of articles. The apparatus provides a barrier to segregate the portion of the article requiring coating from the portion of the article not requiring coating. The fixture is reusable, being unaffected by the coating gases. The fixture reduces the exposure of the coating gases with the portion of the article not requiring coating. By use of an optional seal, the portion of the article not requiring coating can be isolated from the coating gases.Type: GrantFiled: April 25, 2003Date of Patent: November 23, 2004Assignee: General Electric CompanyInventors: Nripendra Nath Das, Raymond William Heidorn, Thomas Edward Mantkowski, Patricia Ann Charles

Patent number: 6620457Abstract: A method of applying a thermal barrier coating system to a metal piece having cooling holes angled in a first direction and cooling holes angled in a second direction. The method includes spraying a bond coat on a first surface of the piece at angles with respect to the first and second directions and to a thickness selected in combination with the angles to prevent the bond coat from entirely filling any of the holes. A thermal barrier coating is sprayed on the bond coat at angles with respect to the first and second directions and to a thickness selected in combination with the angles to prevent the thermal barrier coating from entirely filling any of the holes. The method also includes spraying a high pressure fluid jet from a nozzle assembly through each hole generally parallel to the respective cooling hole.Type: GrantFiled: July 13, 2001Date of Patent: September 16, 2003Assignee: General Electric CompanyInventors: Gilbert Farmer, Thomas John Tomlinson, Raymond William Heidorn, Jeffrey Arnold Fehrenbach, William Lee Imhoff, Myron Edward Rutherford
