Patent number: 7014723Abstract: Castable and weldable nickel-base alloys that exhibit a desirable balance of strength and resistance to corrosion and oxidation suitable for gas turbine engine applications. The alloy contains, by weight, about 10% to about 25% cobalt, about 20% to about 28% chromium, about 1% to about 3% tungsten, about 1.6% to about 3.8% aluminum, about 0.4% to about 1.5% titanium, where the sum of aluminum and titanium is about 1.8% to about 5.0%, about 0.5% to about 1.5% columbium, 0.5% to about 1.5% tantalum, about 0.001% to about 0.025% boron, about 0.05% maximum zirconium, about 0.02% to about 0.15% carbon, with the balance essentially nickel and incidental impurities. The alloy may more preferably contain about 2.8% to about 3.8% aluminum where the sum of aluminum and titanium is about 3.0% to about 5.0%, or about 1.6% to about 2.8% aluminum, where the sum of aluminum and titanium is about 1.8% to about 4.3%.Type: GrantFiled: September 26, 2002Date of Patent: March 21, 2006Assignee: General Electric CompanyInventors: Cyril Gerard Beck, John Herbert Wood, Stephen Daniel Graham

Patent number: 6881439Abstract: An aluminiding process that enables the cooling holes of an air-cooled component, such as a hot gas path component of a gas turbine engine, to be machined and then aluminized after all external surface coatings have been deposited. The aluminide coating is deposited using a slurry process capable of forming the aluminide coating on the component without damaging an existing ceramic coating on the component. The process involves applying an activator-free slurry containing aluminum particles that, when the component is sufficiently heated, melt and diffuse into the component surface to form the diffusion aluminide coating.Type: GrantFiled: December 4, 2002Date of Patent: April 19, 2005Assignee: General Electric CompanyInventors: Stephen Daniel Graham, John Herbert Wood, Cyril Gerard Beck, Warren Tan King

Patent number: 5140264Abstract: The present invention provides a method and apparatus for performing nondestructive material assessment of service exposed combustion turbine blades. According to the invention, the testing is accomplished by inserting eddy current (EC) probes into the blade's cooling holes, and evaluating the eddy current response of the blade. The eddy current probes are preferably coupled together in a differential mode. The measured response is then compared with a previously determined response corresponding with a known material condition. An assessment of the blade is made on the basis of this comparison.Type: GrantFiled: June 24, 1991Date of Patent: August 18, 1992Assignee: Westinghouse Electric Corp.Inventors: Michael J. Metala, C.

Patent number: 4584697Abstract: In a 4-phase CCD with 90.degree. overlap of the clock voltages, the area below two clock electrodes may be used for the storage of charge packets which thus can be 2.times. as large as in conventional modes of operation. By choosing the penultimate electrode before the reading stage to be approximately 2.5.times. as large as the other electrodes, this double charge packet can be transferred undivided in time to the output diode, a feature which is particularly advantageous for further signal processing.Type: GrantFiled: March 19, 1985Date of Patent: April 22, 1986Assignee: U.S. Philips CorporationInventors: Teunis J. Hazendonk, Arend J. Klinkhamer, Gerard A. Beck, Theodorus F. Smit
