Abstract
Description
幾つかの多結晶ダイヤモンド成形体を、以下のように製造した。平均粒径が22μmのダイヤモンド粉末3gを、炭化タングステン基材に接触させて置き、高温高圧で処理した(約1300℃及び5GPa)。焼結後、PDC切削機を、適当な粒度に粉砕し、多結晶ダイヤモンド切削縁部を高速で回転する花崗岩の棒に押し付けることによって摩耗試験にかけた。こうして測定した耐摩耗性を、金属ホウ化物でドープした実施例2〜4のPDC切削機と比較するための基準とした。
実施例1に従って多結晶ダイヤモンド成形体を製造し、ダイヤモンド粉末に対して0.5重量%の量の粒子状二ホウ化アルミニウムを、焼結前に高温高圧で添加した。これらの切削機の耐摩耗性を実施例1で得られたものと比較し、平均で4%の増加が示され、PDC切削機における二ホウ化アルミニウムの存在に起因して、耐摩耗性が改善されたことが示された。
実施例1に従って多結晶ダイヤモンド成形体を製造し、ダイヤモンド粉末に対して0.7重量%の粒子状六ホウ化セリウムを、焼結前に高温高圧で添加した。耐摩耗性は6%の改善を示した。図2に示すように、セリウムの存在をXRF分析によって検出した。
粒子状六ホウ化ランタン0.7重量%を含む多結晶ダイヤモンド成形体を、上記の方法に従って製造し、耐摩耗性は6%の改善を示した。図3に示すように、ランタンの存在をXRF分析によって検出した。
