DOUBLE-LAYER BRAKE DISC IN NICKEL-FREE STEEL AND MANUFACTURING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044384 titled 'DOUBLE-LAYER BRAKE DISC IN NICKEL-FREE STEEL AND MANUFACTURING METHOD

Simplified Explanation

The abstract of the patent application describes a brake disc for a disc brake. The brake disc is made of gray cast iron or steel and has two opposite braking surfaces. The disc is coated with a base layer that is nickel-free and contains one or more carbides. An intermediate layer of nickel-free steel is placed between the base layer and at least one of the braking surfaces.

  • The brake disc is made of gray cast iron or steel.
  • It has two opposite braking surfaces.
  • The disc is coated with a base layer that is nickel-free.
  • The base layer contains one or more carbides.
  • An intermediate layer of nickel-free steel is placed between the base layer and at least one of the braking surfaces.

Potential applications of this technology:

  • Automotive industry: The brake disc can be used in various vehicles, including cars, motorcycles, and trucks, to improve braking performance and durability.
  • Aerospace industry: The brake disc can be utilized in aircraft to enhance braking efficiency and reliability.
  • Industrial machinery: The brake disc can be employed in heavy machinery and equipment to ensure effective braking and prevent accidents.

Problems solved by this technology:

  • Improved braking performance: The inclusion of carbides in the nickel-free steel coating enhances the friction and heat resistance of the brake disc, resulting in better braking performance.
  • Corrosion resistance: The nickel-free steel coating provides protection against corrosion, extending the lifespan of the brake disc.
  • Reduced environmental impact: The absence of nickel in the base layer reduces the environmental impact associated with nickel mining and processing.

Benefits of this technology:

  • Enhanced durability: The combination of gray cast iron or steel with the nickel-free steel coating and carbides increases the longevity of the brake disc, reducing the need for frequent replacements.
  • Improved safety: The improved braking performance of the disc ensures safer and more reliable braking, reducing the risk of accidents.
  • Environmental friendliness: The use of a nickel-free base layer reduces the environmental impact of the brake disc production process.


Original Abstract Submitted

a brake disc for disc brake comprises a braking band made of gray cast iron or steel, provided with two opposite braking surfaces, each of which defines at least partially one of the two main faces of the disc. the brake disc is provided with a base layer totally nickel-free and one or more carbides included in the nickel-free steel, which covers at least one of the two braking surfaces of the braking band. an intermediate layer composed of nickel-free steel is interposed between the base layer and at least one of the two braking surfaces of the braking band.
