  • Patent number: 9322100
    Abstract: A method for manufacturing an abrasive coating on a gas turbine component, especially on a gas turbine rotor blade tip, comprising at least the following steps: a) providing a gas turbine component, especially a gas turbine rotor blade; b) providing a high temperature melting alloy powder; c) providing abrasive particles; d) providing a low temperature melting alloy powder; e) blending at least said high temperature melting alloy powder and said abrasive particles to provide a mixture; f) applying said low temperature melting alloy powder and said mixture to an area of said gas turbine component, especially to a tip of said turbine rotor blade; g) locally heating said area of said gas turbine component to a temperature above the melting point of said low temperature melting alloy powder but below the melting point of said high temperature melting alloy powder is provided.

  • Publication number: 20140272143
    Abstract: The present invention teaches a flame retardation composition. The composition comprises: Ammonium Polyphosphate, Sodium Borate, Boric Acid, 3% Hydrogen Peroxide Solution used as Biocide, and Distilled Water. A homogeneous flame retarding composition solution is processed by mixing the referenced composition compounds in distilled water. The flame retarding composition solution is coated on to be protected substrate surfaces against flame retardation. The materials coated with flame retarding composition solution fully satisfy flammability test under the Federal Aviation Regulation (FAR) 25.853(a) vertical burn test, and Federal Aviation Regulation (FAR) 25.853(d) heat release test. The utility of the present invention extends to numerous commercial and non-commercial applications.

  • Publication number: 20140248434
    Abstract: The present invention teaches a three-step method for an aqua based chemical composition for flame retardation. The composition comprises: Sodium Borate, Boric Acid, Guanylurea Phosphate, Hydrogen Peroxide, Magnesium Chloride, and Sodium Silicate. The referenced salts are dissolved in distilled water, and the resultant flame retarding solution is coated on substrate surfaces to be protected against flame retardation. The flame retarding composition solution from step-1 alone may be used on non-prepared substrate surfaces. The flame retarding composition solution fully satisfies the Federal Aviation Regulation (FAR) 25.853(a) vertical burn test, and Federal Aviation Regulation (FAR) 25.853(d) heat release test. The utility of the present invention extends to numerous commercial and non-commercial applications.
