INTERNAL ALUMINIDE COATING FOR VANES AND BLADES AND METHOD OF MANUFACTURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044256 titled 'INTERNAL ALUMINIDE COATING FOR VANES AND BLADES AND METHOD OF MANUFACTURE

Simplified Explanation

The abstract of this patent application describes a gas turbine engine component that includes a substrate with two surfaces, a plurality of holes extending through the substrate, and a metallic bond coat and aluminide coating on the surfaces and walls of the holes.

  • The gas turbine engine component has a substrate with two surfaces and a plurality of holes that go through the substrate.
  • The holes are defined by walls that extend from one surface to the other.
  • A metallic bond coat is applied to the first surface of the substrate.
  • An aluminide coating is applied to both surfaces of the substrate and the walls of the holes.
  • The metallic bond coat is located between the first surface and the aluminide coating.
  • The walls of the holes do not have the metallic bond coat.

Potential applications of this technology:

  • Gas turbine engines: This component can be used in gas turbine engines to improve their performance and durability.
  • Aerospace industry: The technology can be applied in aircraft engines to enhance their efficiency and reliability.
  • Power generation: Gas turbine engines are used in power plants, and this component can contribute to improving their efficiency and reducing emissions.

Problems solved by this technology:

  • Thermal barrier: The metallic bond coat and aluminide coating provide a thermal barrier, protecting the substrate from high temperatures and improving its longevity.
  • Oxidation resistance: The aluminide coating enhances the component's resistance to oxidation, preventing degradation and extending its lifespan.
  • Bonding strength: The metallic bond coat improves the bonding strength between the substrate and the aluminide coating, ensuring the coating remains intact under operating conditions.

Benefits of this technology:

  • Improved performance: The component's thermal barrier properties and oxidation resistance contribute to enhanced performance and efficiency of gas turbine engines.
  • Increased durability: The technology increases the lifespan of the component by protecting it from high temperatures and oxidation.
  • Cost-effectiveness: By extending the lifespan of the component, maintenance and replacement costs can be reduced, resulting in cost savings for operators.


Original Abstract Submitted

a gas turbine engine component includes a substrate having first surface and a second surface disposed opposite the first surface, a plurality of holes extending through the substrate from the first surface to the second surface, the holes defined by a plurality of respective walls each extending from the first surface to the second surface, a metallic bond coat disposed on the first surface, and an aluminide coating disposed on the first surface, the second surface, and the walls. the metallic bond coat is disposed between the first surface and the aluminide coating and the walls are free of the metallic bond coat.
