まず、本発明の実施形態(以下「本実施形態」とも記す)の概要を以下の(1)〜(5)に列記して説明する。
以下、本実施形態に係る複合焼結体についてより詳細に説明するが、本実施形態はこれらに限定されるものではない。
本実施形態に係る複合焼結体は、第1相と、第2相とを含む複合焼結体であって、第1相は、ダイヤモンド相であり、第2相は、第1相へ歪を付与する1種類以上の元素又は化合物、又はそれら両方で形成される相で形成される相であり、第2相の含有量は、1000ppm以下である。
本実施形態に係る複合焼結体の製造方法は、特に制限はない。耐摩耗性、耐局所摩耗性および耐欠け性の高い複合焼結体を効率よくかつ低コストで製造するため次の工程を含むことが好ましい。
1.原料の準備
原料として黒鉛粉に炭化ケイ素を400ppm添加した混合粉末を準備した。
上記混合粉末を、高温高圧発生装置を用いて、温度2300℃、圧力13GPaで、100分間の焼結条件で、焼結させることにより複合焼結体を得た。
複合焼結体の一断面のSEM観察およびX線回折により、複合焼結体中のダイヤモンド相および第2相を確認および同定した。第2相の含有量は、上記SEM観察から算出したところ、300ppmであった。ダイヤモンド相を形成する粒子の平均粒径は、上記SEM観察から算出したところ、300nmであった。第2相を形成する粒子の平均粒径は、上記SEM観察から算出したところ、60nmであった。複合焼結体のヌープ硬度は、ヌープ圧子を用いて9.8Nの荷重をかけて測定したところ、75GPaであった。また、ダイヤモンド相の線膨張係数は、1.1×10−6/Kであり、炭化ケイ素相の線膨張係数は、6.6×10−6/Kであった。
