Patent number: 7094446Abstract: A method for applying a coating system that is applied to a surface of a component for preventing or at least substantially preventing interdiffusion between the component surface and a protective thermal layer applied to the component surface when the thermal layer is exposed to elevated temperatures. The method includes applying a carrier layer containing aluminum to the component surface. Next, the layer is heated to a first predetermined temperature for a first predetermined period of time in the substantial absence of oxygen to bond the aluminum with the component surface, the heat dissolving the carrier portion of the aluminum layer. The remaining portion of the aluminum layer is then heated to a second predetermined temperature for a second predetermined period of time to form an oxidized aluminum layer. Finally, at least one protective thermal layer is applied over the oxidized aluminum layer.Type: GrantFiled: September 15, 2004Date of Patent: August 22, 2006Assignee: General Electric CompanyInventors: John Frederick Ackerman, Paul Arszman, Andrew J.

Publication number: 20050069647Abstract: A process for depositing pure platinum on a substrate is disclosed. In accordance with one embodiment, the process comprises applying a solution consisting of Pt(acetylacetonate)2 and ethanol or acetone onto a substrate and wrapping at least a portion of the substrate with aluminum foil. The process further comprises heating the substrate wrapped with the aluminum foil to about 300° C. at a rate of about 10-25° C. per minute and then holding at about 300° C. for about 1 hour, wherein the Pt(acetylacetonate)2 decomposes to deposit pure platinum on the substrate.Type: ApplicationFiled: September 29, 2003Publication date: March 31, 2005Inventors: John Ackerman, Paul Arszman

Publication number: 20050048305Abstract: A high temperature gas turbine component for use in the gas flow path that comprises a specular optical reflector coating system. A thin specular optical reflector coating system is applied to the gas flow path of the component, that is, the surface of the component that forms a boundary for hot combustion gases. The component typically includes a thermal barrier coating overlying the high temperature metallic component that permits the component to operate at elevated temperatures. The thermal barrier coating must be polished in order to provide a surface that can suitably reflect the radiation into the gas flow path. The thin reflector coating system comprises a thin high temperature and corrosion resistant refractory stabilizing layer, which is applied over a thin reflective metal layer, which is applied over a thin high temperature and corrosion resistant refractory sealing layer.Type: ApplicationFiled: August 29, 2003Publication date: March 3, 2005Applicant: General Electric CompanyInventors: John Ackerman, Paul Arszman, Bangalore Nagaraj, Nicole Justis

Publication number: 20050039459Abstract: A high temperature splash plate for use in the combustor of a gas turbine engine that also is a specular optical reflector. A thin layer of a high temperature reflector is applied to the surface of the splash plate of the component that forms a boundary for hot combustion gases. The component typically includes a thermal barrier coating overlying the high temperature metallic component that permits the component to operate at elevated temperatures. The thermal barrier coating must be polished in order to provide a surface that can suitably reflect the radiation into the gas flow path. A thin layer of the high temperature reflector then is applied over the polished thermal barrier coating by a process that can adequately adhere the reflector to the polished surface without increasing the roughness of the surface. The surface reflects radiation in the direction of the turbine back into the hot gas flow path. The reflected radiation is not focused onto any other hardware component.Type: ApplicationFiled: December 31, 2002Publication date: February 24, 2005Applicant: General Electric CompanyInventors: John Ackermann, Paul Arszman, Bangalore Nagaraj, Craig Young, Nicole Justis
