摘要:
Hardfacing materials include a polymer matrix material and particles of hard material embedded within and dispersed throughout the polymer matrix material. Earth-boring tools include a tool body and a hardfacing material on at least a portion of a surface of the body, wherein the hardfacing material includes a polymer matrix material and particles of hard material embedded within and dispersed throughout the polymer matrix material. Methods of applying hardfacing material to an earth-boring tool comprise mixing hard particles with a polymer precursor material to form a paste, applying the paste to a surface of an earth-boring tool, and curing the polymer precursor material to form a hardfacing material on the surface of the earth-boring tool.
