A protective coating (2) is applied to the aerofoil (12) and the platform (14) of the turbine blade (10). The protective coating (2) comprises austenitic stainless steel. A chromium oxide layer (22) is formed on the protective coating (2). The protective coating (20) and chromium oxide layer (22) provides oxidation and sulphidation resistance for the titanium aluminide article (10).Type: GrantFiled: April 24, 2000Date of Patent: May 14, 2002Assignee: Rolls-Royce plcInventors: Simon Gray, Clive B. Ponton, Michael H. Jacobs, Hugh E. Evans

Patent number: 6352788Abstract: A thermal barrier coating (TBC) system for components designed for use in a hostile thermal environment, such as the turbine, combustor and augmentor sections of a gas turbine engine. The TBC system employs a thermal-insulating ceramic topcoat that is compatible with known metallic bond coats, such as diffusion aluminides and MCrAlY and NiAl coatings. The ceramic topcoat is formed of zirconia partially stabilized by about one up to less than six weight percent yttria and further stabilized by about one to about ten weight percent of magnesia and/or hafnia, to exhibit improved impact resistance.Type: GrantFiled: February 22, 2000Date of Patent: March 5, 2002Assignee: General Electric CompanyInventor: Robert W. Bruce

Patent number: 6333084Abstract: Durable—long lived plastic films carrying sputter-deposited metal layers such as reflective metal layers on both sides are disclosed. The slip side of the plastic film is not preglowed. The nonslip side is preglowed. This combination of glowing and not preglowing leads to the desired long life.Type: GrantFiled: January 17, 1995Date of Patent: December 25, 2001Assignee: Southwall Technologies, Inc.Inventors: F. Eugene Woodard, Thomas Pass, Ted L. Larsen

Patent number: 6287889Abstract: An improved gas phase synthesized diamond, CBN, BCN, or CN thin film having a modified region in which strain, defects, color and the like are reduced and/or eliminated. The thin film can be formed on a substrate or be a free-standing thin film from which the substrate has been removed. The thin film can be stably and reproducibly modified to have an oriented polycrystal structure or a single crystal structure. The thin film is modified by being subjected to and heated by microwave irradiation in a controlled atmosphere. The thin film has a modified region in which a line width of the diamond spectrum evaluated by Raman spectroscopy of 0.1 microns or greater is substantially constant along a film thickness direction of the thin film, and the line width of the modified region is 85% or less of a maximum line width of the residual portion of the film thickness.Type: GrantFiled: January 26, 2000Date of Patent: September 11, 2001Assignee: Applied Diamond, Inc.Inventors: Shoji Miyake, Shu-Ichi Takeda
