The composition comprises, in parts by weight, from about 20 to 60 parts of an oleaginous material such as a lubricating oil, 10 to 40 parts of organic solvent, 20 to 60 parts of corrosion-inhibitor consisting of a sulfonic acid-carboxylic acid metal complex or a mixture of said metal complex with a small but effective amount of an oil soluble alkyl phosphate, from 0.1 to 2.0 parts of an oil soluble antioxidant, from 0.0 to 5.0 parts of a water-displacing compound, an effective amount of a mildew-inhibiting compound, and from 0.0 to 1.0 part of a heterocyclic metal deactivator.Type: GrantFiled: December 20, 2005Date of Patent: October 26, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventors: El Sayed S. Arafat, Craig A. Matzdorf, James A. Whitfield

Patent number: 7815751Abstract: The invention provides a method and composition for coating a ferrous metal surface with a zirconium/vanadium conversion coating which is substantially free of an organic film forming composition and tannins. The method is a low temperature method which contemplates an aqueous conversion coating composition which is low in phosphates and which comprises zirconium, vanadium, fluoride, as well as phosphate ions in a ratio and a concentration effective for providing a conversion-coated ferrous metal surface.Type: GrantFiled: September 28, 2005Date of Patent: October 19, 2010Assignee: Coral Chemical CompanyInventors: Joseph D. Pemberton, John P. Jandrists

Patent number: 7789953Abstract: An aqueous phosphoric bonding solution consists essentially of phosphoric acid, a source of magnesium ions, and a leachable corrosion inhibitor. The bonding solution is stable with respect to inorganic metal particles, such as aluminum, which are admixed to the bonding solution for the preparation of a coating slurry. Metal parts coated with the coating compositions have very satisfactory properties such as heat and corrosion resistance.Type: GrantFiled: March 28, 2008Date of Patent: September 7, 2010Assignee: Praxair S.T. Technology, Inc.Inventors: Mark F. Mosser, Kevin Eddinger, Eileen Fox, Thomas F. Lewis, III

Patent number: 7776143Abstract: A composition comprising a glass-forming binder component and a particulate corrosion resistant component. The particulate corrosion resistant component comprises corrosion resistant particulates having: a CTEp of at least about 4 and being solid at a temperature of about 1300° F. (704° C.) or greater; and a maximum median particle size defined by one of the following formulas: (a) for a CTEp of 8 or less, an MP equal to or less than (4.375×CTEp)?10; and (b) for a CTEp of greater than 8, an Mp equal to or less than (?4.375×CTEp)+60, wherein CTEp is the average CTE of the corrosion resistant particulates and wherein Mp is the median equivalent spherical diameter (ESD), in microns, of the corrosion resistant particulates. Also disclosed is an article comprising a turbine component comprising a metal substrate and a corrosion resistant coating overlaying the metal substrate, as well as a method for forming at least one layer of the corrosion resistant coating adjacent to the metal substrate.Type: GrantFiled: September 18, 2009Date of Patent: August 17, 2010Assignee: General Electric CompanyInventors: Brian Thomas Hazel, Michael James Weimer
