Publication number: 20020094447Abstract: A method for improving the thermal fatigue life of a thermal barrier coating (TBC) deposited on an aluminide bond coat through a process by which the surface morphology of the aluminide bond coat is modified to eliminate or at least reduce oxidation and oxidation-induced convolutions at the alumina-bond coat interface, as explained more fully below. The bond coat is deposited to have generally columnar grains and grain boundary ridges at its surface, and is then peened at an intensity sufficient to flatten at least some of the grain boundary ridges, but insufficient to cause recrystallization of the bond coat when later heated, such as during deposition of the thermal barrier coating. In so doing, the original surface texture of the bond coat is altered to be smoother where the grain boundaries meet the bond coat surface, thereby yielding a smoother bond coat surface where the critical alumina-bond coat interface will exist following oxidation of the bond coat.Type: ApplicationFiled: January 16, 2002Publication date: July 18, 2002Inventor: Irene Theodor Spitsberg

Patent number: 6372364Abstract: A thin film product having a nanostructured surface, a laminate product including the thin film and a temporary substrate opposite the nanostructured surface, a laminate product including the thin film and a final substrate attached to the nanostructured surface and a method of producing the thin film products. The thin film is particularly useful in the electronics industry for the production of integrated circuits, printed circuit boards and EMF shielding. The nanostructured surface includes surface features that are mostly smaller than one micron, while the dense portion of the thin film is between 10-1000 nm. The thin film is produced by coating a temporary substrate (such as aluminum foil) with a coating material (such as copper) using any process. One such method is concentrated heat deposition or a combustion, chemical vapor deposition process.Type: GrantFiled: August 18, 1999Date of Patent: April 16, 2002Assignee: MicroCoating Technologies, Inc.Inventors: Andrew T.
