Baker Hughes had five patents in advanced materials during Q4 2023. Baker Hughes Co filed patents in Q4 2023 related to polycrystalline compacts for earth-boring tools. The compacts consist of superabrasive material grains of different sizes dispersed in a continuous matrix. Methods include coating larger grains with smaller grains, forming a green structure, and sintering. Another method involves mixing diamond grains with a catalyst and subjecting them to high pressure and temperature to form polycrystalline diamond compacts.

The patent filed by Baker Hughes Co. describes methods for forming polycrystalline compacts with a unique structure involving larger grains of superabrasive material coated with smaller grains, forming a continuous matrix. The process includes sintering the green structure at specific pressure and temperature conditions to prevent grain growth and shrinkage, resulting in inter-granular bonds and non-contiguous larger grains within the matrix. Additionally, there are claims related to selecting diamond as the superabrasive material, mixing catalysts, and utilizing specific materials for the grains.
Furthermore, the patent details a method specifically for forming polycrystalline diamond compacts by mixing diamond grains with a catalyst and controlling sintering parameters to create a compact with in-situ nucleated diamond grains. The process aims to prevent growth and shrinkage of grains, forming a continuous matrix with non-contiguous grains. Claims include forming the compact with specific percentages of direct physical contact between grains, minimizing interstitial spaces filled with the catalyst, and ensuring the larger and smaller grains are of the same superabrasive material. These methods offer innovative approaches to enhancing the properties and performance of polycrystalline compacts for various applications, particularly in earth-boring tools.
