摘要： A metal matrix composite (MMC) may be formed with two or more portions each having different reinforcing particles that enhance strength, wear resistance, or both of their respective portions of the MMC. Selective placement of the different reinforcing particles may be achieved using magnetic members. For example, in some instances, forming an MMC may involve placing reinforcement materials within an infiltration chamber of a mold assembly, the reinforcement materials comprising magnetic reinforcing particles and non-magnetic reinforcing particles; positioning one or more magnetic members relative to the mold assembly to selectively locate the magnetic reinforcing particles within the infiltration chamber with respect to the non-magnetic reinforcing particles; and infiltrating the reinforcement materials with a binder material to form a hard composite.

摘要： An example mold assembly for fabricating an infiltrated downhole tool includes a mold defining a bottom of the mold assembly and a funnel operatively coupled to the mold. An infiltration chamber is 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 downhole tool. A thermal mass is positioned within the infiltration chamber above the infiltrated downhole tool for imparting heat to the infiltrated downhole tool following an infiltration process.

摘要： An example cooling system for a mold assembly includes a quench plate that defines one or more discharge ports and one or more recuperation ports. A fluid is circulated from the one or more discharge ports to the one or more recuperation ports to cool the mold assembly. A blocking ring is positioned on the quench plate and defines a central aperture for receiving a bottom of the mold assembly. An insulation enclosure having an interior for receiving the mold assembly is positioned on the blocking ring. The blocking ring prevents vapor generated by the fluid contacting the bottom of the mold assembly from migrating into the interior of the insulation enclosure.
