Description
具体的には以下の手順で試験を行った。
まず、直径33mmのSi基板上にMOD(Metal Organic Decomposition)塗布型Y-Ceコート溶液として、株式会社高純度化学研究所製のMOD塗付型Y-03とCe-03を酸化物換算でCeO2が原子比で1〜5%と所定比となるように混合したものをスピンコーターにより回転速度1500rpmで60秒間塗付を行った。
塗付を行った後に、サンプルをIR炉(遠赤外線加熱炉)を用いて加熱した。
初めにコート材中の有機物成分を除去するために、IR炉を400℃まで5℃/minの昇温速度で昇温し、5Torr(6.7×102Pa)減圧下でN2ガスを1L/minフローさせた状態で行い、400℃で8時間保持した。
その後、圧力を大気圧まで戻した後に100%O2の雰囲気下で1時間酸化を行った。
酸化を行った後は室温まで自然冷却を行った。
以上の手順により、基板上に表面保護膜を形成したサンプルを作製した。
次に、サンプルを以下の手順で腐食性の高い100%Cl2ガスに暴露した。
まず、内表面をAl2O3処理したSUS配管内部にサンプルをセットし、1000L/minでN2フローを行いながら5℃/minで150℃まで昇温した後、150℃で1時間保持し、サンプル表面に吸着した水分を除去した。
次に、N2ガスをCl2ガスに切替え、圧力3kgf/cm2(2.9×104Pa)で24時間暴露を行った。
次に、Cl2ガスに暴露したサンプルについて、日本電子株式会社(JEOL)製の光電子分光装置(XPS、X-ray Photoelectron Spectroscopy)であるJPS−9010−MXによりClの検出深さ(侵入量)を測定した。
具体的には直径1mm範囲について面内任意3ケ所の測定を行い、平均値をとった。
