Patent number: 7901788Abstract: CVD aluminide coatings including a small concentration of a reactive, gettering element for surface active impurities dispersed therein are formed for improved oxidation resistance. The aluminide coatings are formed by CVD codeposition of Al and the gettering element on the substrate using coating gases for the gettering element generated either outside or inside the coating retort depending on the chlorination temperature needed for the particular gettering element.Type: GrantFiled: August 20, 2003Date of Patent: March 8, 2011Assignee: Howmet CorporationInventors: Bruce M. Warnes, David C. Punola, Jeffery S. Smith, Daniel L. Near

Patent number: 5922148Abstract: Directionally solidified superalloy components having a bulk sulfur concentration of less than 1 part per million by weight are provided by vacuum melting a charge to form a superalloy melt, desulfurizing the melt by contact with a calcium-bearing desulfurizing agent for a time to reduce sulfur concentration of the melt to less than 1 ppm by weight, casting the melt directly or following solidification and remelting in a ceramic investment mold, and directionally solidifying the melt as cast components without adverse bulk sulfur pick-up subsequent to desulfurization to provide castings having a sulfur content below 1 ppm, such as in the range of hundreds of parts per billion to provide significantly improved oxidation resistance.Type: GrantFiled: February 25, 1997Date of Patent: July 13, 1999Assignee: Howmet Research CorporationInventors: Jeffrey D. Irvine, Russell G. Vogt, Donald L. Bierstine, Christine M. Stabile, John R. Mihalisin, Jeffery S. Smith, John P. Kunkle, Gail R. Cole, Thomas W. Nielsen

Patent number: 5462013Abstract: A chemical vapor deposition (CVD) apparatus comprises a reactor having a coating chamber at elevated temperature, means for supporting substrates to be coated at different zones in the coating chamber, and means for supplying a gaseous reactant stream to the chamber for distribution to the coating zones in a manner that the stream is heated to substantially different temperatures at different coating zones. Reactivity-altering material is disposed at the coating zones for contact by the reactant stream supplied thereto before the reactant stream contacts a substrate at the zones. The reactivity-altering material includes a composition that differs between coating zones in dependence on the reactant stream temperatures at the coating zones as necessary to alter the reactivity of the reactant (i.e., activity of a particular chemical specie of the reactant stream) stream at the coating zones in a manner to provide substantially the same reactant reactivity at all coating zones.Type: GrantFiled: October 26, 1993Date of Patent: October 31, 1995Assignee: Howmet CorporationInventors: David C. Punola, William C. Basta, Jeffery S. Smith

Patent number: 5407704Abstract: Chemical vapor deposition apparatus comprises a reactor having a chamber with a coating region for coating a substrate and an exhaust region communicating with the coating region. The coating region includes an inlet for introduction of a gaseous reactant stream to pass over the substrate to react therewith to form a coating thereon and a spent gas stream. The exhaust region includes an outlet for exhausting the spent gas stream from the coating region. The substrate is supported in the coating region and heated to an elevated reaction temperature by suitable support means and heating means. A condensing assembly is disposed in the exhaust region for condensing excess, unreacted gaseous reactant from the spent gas stream before entry into the outlet. The condensing assembly includes a high surface area, apertured structure disposed in the exhaust region where the temperature of the spent gas stream is sufficiently reduced to condense excess, unreacted gaseous reactant therefrom.Type: GrantFiled: August 26, 1993Date of Patent: April 18, 1995Assignee: Howmet CorporationInventors: William C. Basta, David C. Punola, Daniel L. Near, Jeffery S. Smith
