Abstract
【解決手段】比較的平滑な表面が得られる水素含有非晶質炭素被膜において、この水素含有非晶質炭素被膜中に同じ非晶質の炭素微粒子を分散して、平滑な表面と被膜全体の硬度を維持したまま耐欠け性を向上させる。具体的には、アーク放電によってアーク式蒸発源の炭素カソードより放出される微粒子を被膜中に取り込むことによって、水素含有非晶質炭素被膜に同じ非晶質の炭素微粒子を分散する。

Description
実施例1
まず、基材として用いる硬化処理を施した高速度工具鋼(JIS G4403規格材のSKH51材)の円板(φ24 mm、厚さ4 mm)の一方の表面を、表面粗さRz(JIS B0601 ’94の10点平均粗さ)が0.3〜0.5μmになるように研磨加工した。成膜開始直前に、アセトン及びエタノールで順次超音波洗浄を行い、表面に付着した汚れを除去した。クロム(Cr)カソードとグラファイトカソードを備えた反応性アークイオンプレーティング装置内に上記円板をセットし、真空排気した後、イオンボンバード処理を実施し、続いてCr中間層を形成した。次に、アルゴンガス及びアセチレンガスを導入し、アーク放電電流を80Aに設定し、アーク放電によってグラファイトカソード(炭素98at%以上)を蒸発させながら、ピーク電圧−50V、周波数250kHz、ON/OFF比1.0のパルスバイアスを印加する条件で反応性アークイオンプレーティング法によって硬質炭素被膜を形成した。得られた被膜の膜厚は約7μmであった。
実施例1のクロム(Cr)カソードをチタン(Ti)カソードに変更した以外は実施例1と同じ条件でTi中間層を形成した。その後は、実施例1のアルゴンガス及びアセチレンガスの代わりに水素ガス及びメタンガスを導入し、実施例1と同じバイアス条件で反応性アークイオンプレーティング法によって硬質炭素被膜を形成した。なお、アーク放電電流は65Aに設定した。
実施例1と同じ円板基材を装置内にセットし、まず、アルゴンガスとテトラメチルシラン(TMS)ガスを導入し、プラズマCVD法により炭化珪素(SiC)中間層を形成した。その後、アルゴンガス及びベンゼンを導入し、10Pa以下の減圧状態でピーク電圧−100V、周波数200kHz、ON/OFF比0.3のパルスバイアスを印加する条件で反応性アークイオンプレーティング法によって硬質炭素被膜を形成した。なお、アーク放電電流は100Aに設定した。
実施例1と同じ条件でCr中間層を形成し、そしてアルゴンガス及びアセチレンガスを導入し、反応性アークイオンプレーティング法によって硬質炭素被膜を形成した。なお、アーク放電電流45Aに設定した。
実施例1と同じ材質、寸法、研磨加工及び洗浄処理を行った円板基材を装置内にセットし、中間層を形成することなく、アルゴンガスとアセチレンガスを導入し、基材に周波数250 kHz、電圧−320V、ON/OFF比1.0のパルスバイアスを印加して高周波放電プラズマを励起し、プラズマCVD法により硬質炭素被膜を形成した。
実施例2と同じ条件でTi中間層を形成し、水素ガス及びメタンガスを導入し、グラファイト製カソードを用い、実施例1と同じバイアス条件で反応性スパッタリング法により硬質炭素皮膜を形成した。
アーク放電電流を120Aに設定した以外は、実施例1と同じ条件で反応性アークイオンプレーティング法を利用して硬質炭素被膜を形成した。
実施例2と同じ条件で、蒸発源の機構のみ変更し、磁気フィルタを備えるアーク式蒸発源を適用した反応性フィルタードアークイオンプレーティング法を利用して硬質炭素被膜を形成した。
