The fine-grained and/or amorphous metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling although the coefficient of linear thermal expansion (CLTE) of the metallic layer and the substrate are mismatched. The interface between the metallic layer and the polymer is suitably pretreated to withstand thermal cycling without failure.Type: ApplicationFiled: May 24, 2010Publication date: December 2, 2010Applicant: INTEGRAN TECHNOLOGIES, INC.Inventors: Klaus Tomantschger, Jonathan McCrea, Nandakumar Nagarajan, Francisco Gonzalez, Gino Palumbo, Konstantinos Panagiotopoulos, Herath Katugaha, Diana Facchini, Jared J.

Patent number: 7842335Abstract: A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a paste-like mixture of a ceramic composition comprising ceramic powders and nano-sized ceramic materials in a binder, further including an accelerant, is applied to the surface area of the component, and is optionally smoothed using mechanical means. The composition is then allowed to dry and cure to form a dried coating having polymeric characteristics. Upon subsequent heating, the dried coating reacts to produce a glassy ceramic repair coating.Type: GrantFiled: June 29, 2005Date of Patent: November 30, 2010Assignee: General Electric CompanyInventors: Andrew Jay Skoog, Jane Ann Murphy, William Randolph Stowell, David E.
