摘要:
A mold assembly and method for fabricating an infiltrated drill bit may comprise a mold forming a bottom of the mold assembly, a funnel operatively coupled to the mold, an infiltration chamber defined at least partially by the mold and the funnel to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated drill bit, a displacement core arranged within the infiltration chamber and having one or more legs that extend therefrom, a metal blank arranged about the displacement core within the infiltration chamber, and one or more thermal elements. A method may comprise providing a mold assembly having component parts that include a mold that forms a bottom of the mold assembly and a funnel operatively coupled to the mold, imparting thermal energy to the infiltration chamber with one or more thermal element, and heating contents contained within the infiltration chamber.
