Description
LVA放電電流 110A
アルゴン流量 50sccm
水素流量 300sccm
というパラメータが設定された。
アルゴン流量 60sccm
LVA放電電流 150A
バイアス電圧 60V(DC)
というパラメータが設定された。
窒素流量 総圧力3Paに調整
Crターゲット毎の電流 140A
DC基材バイアス電圧 U= −20V
であった。
上記説明のようにして、スチールピストンのピストンクラウンのボウルエッジにPVD法によりコーティングした。第1に3.9μm厚のCrN接着層、続いて各々約0.06μmの厚さを有して交互に付着された23のCrN層と23のCrON層とからなる機能層という構成のコーティングであった。接着層上に付着された機能層のうちの第1層は、ここではCrN層であった。機能層の全膜厚は、約2.9μmであった。図1は、得られたコーティングの成膜状態を示し、図1(b)はコーティングされたピストンの断面図を、図1(a)及び図1(c)は各々図1(b)によるスチールピストンの断面顕微鏡写真をそれぞれ示す。
実施例1で使用されたスチールピストンで、ただし保護層を付着せずに、実施例1と同じテスト走行を実施した。図3(a)及び図3(b)から分かるように、コーティング無しのスチールピストンの材料は、上記不利益を引き起こすスケールきずを有する。
