  • Method for preparing high-entropy alloy composites reinforced by diamond particles
    Patent number: 11761063
    Abstract: Disclosed is a method for preparing a high-entropy alloy composites reinforced by diamond particles, belonging to the technical field of metal composites preparation. A vacuum coating preparation equipment equipped with an in-situ heating sample stage is used to perform a treatment of high-entropy alloy metallizing coating on the surface of diamond particles to generate modified diamond particles, where the alloy of the coating includes any four, five or six elements among seven elements of Ti, Zr, Hf, Nb, Ta, W and Mo in an equal atomic proportion. The obtained coating generates carbide film in-situ with the surface layer of diamond particles, while the high-entropy alloy covers the carbide film, ensuring a strong bond with the diamond, and the high-entropy alloy composites reinforced by diamond particles are finally prepared.
