Description
前記熱分解炭素層における少なくとも一部の表面に、熱分解炭素のクラスターが複数形成されていることを特徴とする炭素複合部材。
また、本発明に係る炭素複合部材は、その使用時に他の部材と固着しても、固着するのは、熱分解炭素層表面における熱分解炭素のクラスターのみであるため、他の部材から容易に分離可能であり、熱分解炭素層へのダメージが小さくなる。
また、本発明に係る炭素複合部材は、その使用時に他の部材と固着しても、固着するのは、熱分解炭素層表面における熱分解炭素のクラスターのみであるため、他の部材から容易に分離可能であり、熱分解炭素層へのダメージが小さくなる。
図1は、本発明の実施の形態に係る炭素複合部材の断面模式図である。本実施形態に係る炭素複合部材1は、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における少なくとも一部の表面に、熱分解炭素のクラスター4、すなわち、熱分解炭素を原料とするパーティクルの沈積物が複数形成されている。
更には、本実施形態に係る炭素複合部材1は、その使用時に他の部材と固着しても、固着するのは、熱分解炭素層3の表面における熱分解炭素のクラスター4のみであるため、他の部材から容易に分離可能であり、熱分解炭素層3へのダメージが小さくなる。
熱分解炭素のクラスター4の大きさは、熱分解炭素層3の表面に付着したクラスター4をそのまま測定してもよく、数が多く個々のクラスター4の判別がつかない場合には、クラスター4を剥ぎ取って確認する。クラスター4を剥ぎ取って確認する場合には、粘着テープの表面に固定して電子顕微鏡で拡大し、サイズを測定することができる。
算術表面粗さRaが1μm以上であると、クラスター4が熱分解炭素層3の中に埋没しにくくなり、固着の防止や滑り止め効果が発揮されやすい。一方、算術平均粗さRaが3μm以下であると、炭素複合部材1の寸法に与える影響が小さく、寸法精度の高い部材として使用することができる。
また、本実施形態において、上記算術平均粗さRaを求めるにあたっては、基準長さを0.5mmとし、熱分解炭素層3の表面における任意の3箇所で測定した算術平均粗さRaの平均値でもって判断するものとする。
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、熱分解炭素層3を黒鉛基材2の表面に成膜する。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。
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以下になるように供給して、熱分解炭素層の形成を開始させた。
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、原料ガスの供給を急激に停止した。
このようにして、空中で形成された熱分解炭素のパーティクルを熱分解炭素層の表面に沈積させた。なお、このような希薄な雰囲気ガスの瞬間的な温度の変動の有無は、熱電対放射温度計で検出しにくく、熱分解炭素のクラスターの生成の有無で確認することができる。
この炭素複合部材をラテックスからなる防塵手袋を着用し、表面の摩擦を確認したが、強い力が加わっても十分保持できることが確認できた。
実施例1と同様に炭素複合部材を形成した。ただし、熱分解炭素層の形成後、原料ガスの供給を10分間かけて徐々に絞った。このため、原料ガスの供給ストップによる急激な温度上昇は平準化され、クラスターの生成は起きなかったと考えられる。
この炭素複合部材をラテックスからなる防塵手袋を着用し、熱分解炭素層が形成された面を掴んで持ち上げたが、表面の摩擦力だけでは滑りやすく強い力が加わると十分保持できないことが確認された。
