Abstract:
An article includes a working portion including cemented carbide, and a heat sink portion in thermal communication with the working portion. The heat sink portion includes a heat sink material having a thermal conductivity greater than a thermal conductivity of the cemented carbide. Also disclosed are methods of making an article including a working portion comprising cemented carbide, and a heat sink portion in thermal communication with the working portion and including a heat sink material having a thermal conductivity that is greater than a thermal conductivity of the cemented carbide. The heat sink portion conducts heat from the working portion.
