HIGH-ENTROPY ALLOY COATING AND PREPARATION METHOD AND USE THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240254599 titled 'HIGH-ENTROPY ALLOY COATING AND PREPARATION METHOD AND USE THEREOF

The patent application describes a high-entropy alloy (HEA) coating and its preparation method and use. Laser cladding is used with an HEA powder to create the coating, with the HEA being a FeCoCrNiAlTi alloy with specific chemical components in atomic percentage.

• The HEA material has high hardness and wear resistance, making it suitable for laser cladding on precision molds, offshore components, or drilling rods.
• The alloy components are prepared into a powder and then transformed into a high-strength, high-hardness, and wear-resistant HEA coating through laser cladding.
• The material has excellent weldability and is a special nickel-based HEA material ideal for laser additive manufacturing.

1. 1. 1. Potential Applications:

The HEA coating can be used in precision molds, offshore components, and drilling rods where high hardness and wear resistance are required.

1. 1. 1. Problems Solved:

The technology addresses the need for materials with high hardness and wear resistance for various industrial applications.

1. 1. 1. Benefits:

The HEA coating provides high strength, high hardness, and excellent wear resistance, enhancing the durability and performance of coated surfaces.

1. 1. 1. Commercial Applications:

"High-Entropy Alloy Coating for Industrial Applications" - This technology can be commercialized for use in precision mold manufacturing, offshore equipment, and drilling industries, improving the longevity and performance of components.

1. 1. 1. Questions about High-Entropy Alloy Coating:
         1. 1. How does the HEA coating compare to traditional coatings in terms of wear resistance?
