Description
[0098]図5は、本発明方法の幾つかの態様にしたがって製造した複合体物品70の写真である。物品70は、金属マトリクス中に分散している硬質無機粒子を含む接合相74によって結合されている数個の個々の焼結超硬合金片72を含む。個々の焼結超硬合金片72は、通常の技術によって製造した。超硬合金片72を円筒形の黒鉛成形型内に配置し、片72の間に非占有空間を画定した。鋳造炭化タングステン粒子を非占有空間内に配置し、個々の炭化タングステン粒子の間に残余空間を存在させた。超硬合金片72及び鋳造炭化タングステン粒子を含む成形型を1180℃の温度に加熱した。溶融青銅を成形型の空洞部中に導入し、残余空間に浸潤させて、超硬合金片及び鋳造炭化タングステン粒子を結合させた。青銅の組成は、78%(w/w)の銅、10%(w/w)のニッケル、6%(w/w)のマンガン、及び6%(w/w)のスズであった。青銅を冷却及び凝固させて、固体青銅中に埋封している鋳造炭化タングステン粒子の金属マトリクス複合体を形成した。
[0100]図7は、本発明方法の複数の態様にしたがって製造した更なる複合体物品80の写真である。物品80は、共晶組成を有するNi−WC合金82によって物品80中に結合されている2つの焼結超硬合金片81を含む。物品80は、2つの超硬合金片81の間の面取りされた領域内に55%(w/w)のニッケル粉末及び45%(w/w)の炭化タングステン粉末から構成される粉末ブレンドを配置することによって製造した。アセンブリを、真空炉内において、粉末ブレンドの融点より高い1350℃の温度で加熱した。面取りされた領域内において溶融材料を冷却してNi−WC合金82として凝固させ、超硬合金片81を結合させて物品80を形成した。
