Abstract
Description
前記熱分解炭素層は、前記熱分解炭素層と前記黒鉛基材との界面近傍に、気孔が存在する領域を有することを特徴とする炭素複合部材。
前記最大気孔径が、50μmの区間における、前記黒鉛基材の頂部及び底部との最大高低差の30%以下である。
本実施形態に係る炭素複合部材1は、図1に模式的に示すように、黒鉛基材2上に熱分解炭素層3が形成され、更に、熱分解炭素層3は、熱分解炭素層3と黒鉛基材2との界面近傍に、気孔4が存在する領域を有する。なお、気孔4が存在する領域には、気孔径が一定ではない複数の気孔4がランダムに存在している。
これらの効果をより良好に発揮させるためには、熱分解炭素層3の厚さは10〜100μmがより好ましく、20〜50μmが更に好ましい。
そして、成膜温度を保持し、一定時間原料ガスを導入することで、ごく薄い熱分解炭素層3を黒鉛基材2の表面に成膜する(図3(b))。なお、キャリアガスとしては、Ar等の不活性ガスを用いることができる。なお、このごく薄い熱分解炭素層は、任意であり形成しなくてもよい。
以下、本発明に係る炭素複合部材の特徴が明確になるように、実施例及び比較例を挙げて更に説明する。
等方性黒鉛材料を、50×50×5mmのサイズとなるように加工し、黒鉛基材とした。得られた黒鉛基材をCVD炉内に置き、真空ポンプで減圧しながら1200℃以上に加熱し、炭化水素からなる原料ガスを、CVD炉内のガス圧が1kPa以下になるように最初から一定のガス分圧で原料ガスを供給して、熱分解炭素層の形成を開始させた。なお、成膜時は、継続して炭化水素ガスが消費されるので、定常状態では供給するガスと炉内のガスを比較すると、炉内のガスの方が炭化水素のガス分圧が低くなっている。
このため、成膜から一定の炭化水素ガスの分圧を維持して供給すると、成膜の初期において炭化水素ガスのガス分圧が高い状態ができ、黒鉛基材の表面に気孔を形成するクラスターができやすくなると考えられる。
続いて、熱分解炭素層の厚さが20μmに成長する時間に達した時点で、原料ガスの供給を停止した。
また、黒鉛基材及び熱分解炭素層の積層方向に沿った断面視において、上記最大気孔径が、50μmの区間における、前記黒鉛基材の頂部及び底部との最大高低差の19%であった。なお、黒鉛基材の頂部及び底部との最大高低差は5.5μmであった(図5の破線部分)。
実施例1と同様に炭素複合部材を形成した。ただし、最初は炭化水素ガスの比率を少なくし、徐々に炭化水素ガスの流量を増やした後、実施例1と同様に一定の原料ガスの分圧比で製膜を行った。
