Description
前記中間層上に形成され、ナノインデンテーション硬度が25GPa以上35GPa以下で、かつ膜厚が0.3μm以上1.0μm以下であるダイヤモンドライクカーボン膜とを備えているところに特徴を有する。
中間層、DLC膜の硬度は、前記条件で基材上に中間層を約7μm形成した試料、前記条件で基材上にDLC膜を約1μm形成した試料をそれぞれ作製し、ナノインデンテーション法で測定した。測定には、超微小押し込み硬さ試験機(「ENT−1100a」、ELIONIX社製)を用い、ダイヤモンド製のBerkovich圧子を用い、測定荷重10〜100mNの範囲で負荷−除荷曲線を測定し、硬度を算出した。
摺動試験は、図1に示す通り、スラスト玉軸受け(NTN社製51104を使用)上で、前記試料(中間層2、密着性強化層(図示せず)およびDLC膜3が形成されたSKD51ディスク1)を回転させるリングオンボール試験装置を用いて実施した。ボール5を3個に減少させ、かつ荷重:950Nの条件で試験することで、面圧が4.7GPaの条件を実現した。回転数は1500rpmとした。また、無潤滑の条件で試験した。油中やグリース塗布などの潤滑環境下では、前記条件で試験時間を20時間以上としても優劣の判断が難しいため、前記無潤滑とすることで加速試験を行った。尚、図1において、4はボール保持具、6はスラスト玉軸受け用軸受けレース、7はディスク保持部、8は軸受けレース保持部、9は回転軸を示している。
