Patent number: 7514153Abstract: A method is provided for coating a steel surface of a workpiece. According to an aspect of the invention, a steel workpiece is subjected to a first embrittlement-relief baking operation to form a protective oxide layer on the steel surface. The protective oxide layer is de-scaled, and the steel surface is activated. A hydrogen barrier coating is deposited on the activated steel surface, and activated. A zinc-nickel alloy is plated on the barrier coating, and subjected to a second embrittlement-relief baking operation. The porous plating is sealed with a conversion coat. The method is especially useful in making low to no hydrogen embrittlement cadmium-replacement steel parts. Also provided is a corrosion resistant coated steel workpiece.Type: GrantFiled: March 3, 2005Date of Patent: April 7, 2009Assignee: The United States of America as represented by the Secretary of the NavyInventors: Harry L. Archer, Jr., Wayne J. Powell, Josephs T. Menke

Patent number: 7510779Abstract: A coated article is prepared by furnishing a nickel-base article substrate having a free sulfur content of more than 0 but less than about 1 part per million by weight. A protective layer is formed at a surface of the article substrate. The protective layer includes a platinum aluminide diffusion coating. The protective layer may be substantially yttrium-free, or have a controlled amount of yttrium. A ceramic layer may overlie the protective layer.Type: GrantFiled: September 17, 2004Date of Patent: March 31, 2009Assignee: General Electric CompanyInventors: William Scott Walston, Jon Conrad Schaeffer, Wendy Howard Murphy

Patent number: 7507484Abstract: A thermal barrier coating (TBC) system (450) capable of self-healing has a substrate (420), a metal-based advanced bond coat (435) overlying the substrate and a ceramic top coat (440) overlying the bond coat. The bond coat (435) comprises ceramic oxide precursor materials capable of forming a non-alumina ceramic oxide composition when exposed to a thermally conditioning oxidizing environment. Embodiments of such bond coat (435) comprise rare earth elements in a range of 1-20 weight percent, and Hf in a range of about 5 to 30 weight percent or Zr in a range of about 2 to 20 weight percent. Examples of self-healing TBC systems (400, 402, 404) are provided using such bond coat (435) or its advanced bond coat chemistries in combination with conventional bond coats (433, 437) or conventional bond coat chemistries.Type: GrantFiled: December 1, 2006Date of Patent: March 24, 2009Assignee: Siemens Energy, Inc.Inventors: Anand A. Kulkarni, Ramesh Subramanian, Andrew J. Burns

Patent number: 7501187Abstract: An outwardly grown diffusion aluminide bondcoat is formed on a superalloy substrate and has higher concentrations of Al and Pt and lower concentrations of harmful impurities (e.g. Mo, W, Cr, Ta, S, etc.) at an outermost region of the bondcoat than at an innermost region thereof adjacent the substrate. The bondcoat is pretreated prior to deposition of a ceramic thermal insulative layer in a manner that reduces grain boundary ridges on the outermost bondcoat surface without adversely affecting the outermost region thereof, and then is heat treated to thermally grow a stable alpha alumina layer on the bondcoat prior to deposition of a ceramic layer.Type: GrantFiled: September 24, 2002Date of Patent: March 10, 2009Assignee: Howmet Research CorporationInventors: Bruce M. Warnes, Joel Lee Cockerill, John Edward Schilbe
