Abstract
Description
一方、アルミ単層のコーティング材に▲2▼水素ガス暴露チャージ方法の温度を100℃と270℃で変えた場合の水素量測定結果を比較する(No.2,4)。これらはいずれも水素カット率がそれぞれ50%と51%で明確な差がない。水素は温度が高くなるほど拡散係数が高くなる。それにも関わらず水素カット率に差が見られないのは、コーティング部の膜厚ではなくコーティング部と母材の間の界面に水素侵入抑制の因子があることを示している。このように界面自体が重要な因子であることを考えると、アルミ単層のスパッタ法においては膜厚を変えても水素カット率は変わらないものと考えられる。したがって、アルミ単層のコーティングでは水素カット率をこれ以上増加させることはできないが、鉄の微粉末を混合させることでコーティング部自体に界面が増え、水素カット率が増加する。
