Abstract
Description
・非金属の触媒/溶媒で焼結されたPCD
・浸出させたPCD、及び
・焼結されたセラミックマトリックス中のダイアモンド粒子、特に、ケイ素ベースのセラミックマトリックス中のダイアモンド
等の、様々な材料種から選択され得る(しかしそれらに限定されるものではない)。
・例えば、アルカリ金属又はアルカリ土類金属の炭酸塩、硫酸塩又は水酸化物塩等の、非金属の触媒/溶媒の存在下で焼結されたPCD
・浸出させたPCD、すなわち、金属相が、いくつかの種類の物理化学的処理により次いで大部分除去された、標準的な金属の触媒/溶媒を用いて生成されるPCD材料、及び
・セラミックマトリックスが、酸化物、窒化物、炭化物、及びそれらの任意の組合せであり得る、焼結されたセラミックマトリックス中のダイアモンド粒子
等の、様々な材料の種類から選択され得る(しかしそれらに限定されるものではない)。
浸潤させ、ダイアモンド粒と反応させるための元素ケイ素を用いて従来の熱安定性のPCD成形体を製造して、高圧及び高温の条件下でSiC−ダイアモンド成形体を製造した。この場合におけるダイアモンド粒は、約20μm大であった。この成形体は、炭化物の基材により支持されていなかった。次いで、焼結された本体は、破砕及び粉砕されて、凝集した又は焼結されたTSPCDの微粒子又は顆粒を生成した。次いで、これらの微粒子又は顆粒を篩いにかけて、所望の大きさ、すなわち50から150μmの間の予備焼結した粒子又は顆粒を得た。
実施例1と同様に、TSPCDの微粒子又は顆粒を、約6μm大のダイアモンド粒により調製し、30から100μmの間の所望の大きさに篩った。
