前記皮膜中の炭素の全結合に占める、炭素と炭素の結合比率(y)が0.2以上である硬質皮膜を製造する方法であって、
磁力線がターゲットの蒸発面にほぼ直交して基材の方向に発散する磁場の形成されるアーク式蒸発源を用い、前記ターゲットの蒸発面における最も強い磁場の強さが70ガウス以上となるように、前記磁場を形成し、炭化水素ガスおよび窒素ガスを含有する雰囲気ガス中でアーク放電を行って前記硬質皮膜を形成するところに特徴を有する。

上述した通り、C−C結合を一定以上含む本発明の硬質皮膜を形成するには、本発明で規定する方法で成膜することが有効である。即ち、磁力線がターゲットの蒸発面にほぼ直交して基材の方向に発散する磁場の形成されるアーク式蒸発源を用い、炭化水素ガスおよび窒素ガスを含有する雰囲気ガス中でアーク放電を行って前記硬質皮膜を形成する方法である。このときアークイオンプレーティング(AIP)装置において、後述する通り、磁場形成手段である磁石がターゲットの蒸発面よりも前方(基材側)に配置されて、ターゲット蒸発面にほぼ直交して前方に(即ち、基材方向に向かって)磁力線が発散していることが、本発明の硬質皮膜を形成する上で大変有効である。
図2に示す装置であって、図3〜5に模式的に示す磁力線を形成する磁場形成手段を有するアーク式蒸発源を含む装置を用いて皮膜を形成した。ターゲットとしてTiを使用し、Ar(放電安定用)+N2+アセチレン(C2H2)の雰囲気ガス中で、下記の条件にてアーク放電を行った。また、前記皮膜の形成は、表1に示す通りC2H2分圧を変化させて、C量(a)とC−C結合比率(y)が各々異なるTi(CN)皮膜(膜厚はいずれも3000nm)を鏡面の超硬基板上に形成した。尚、ターゲット蒸発面における最も強い磁場(ターゲット中心部の磁場)は、表1に示す通り、蒸発源として図3に示す従来の形式のアーク式蒸発源2Aを使用した場合が約10ガウス、蒸発源として図4に示す推奨される形式のアーク式蒸発源2を使用した場合が約70ガウス、蒸発源として図5に示す推奨される他の形式のアーク式蒸発源2Bを使用した場合が約90ガウスであった。
