Description
1.金属亜鉛への酸の攻撃(pH5から7の間のSO4 2−溶液)。これは、Zn2+イオンの生成および媒体のアルカリ化につながる。Zn+2H2O→Zn2++2OH−+H2。
試験片を2種類のタイプの薄板1から切り出す。即ち
−薄板1。この被覆7には、5.5μm厚の亜鉛の層11および厚さ3.5μmの層9が含まれ、これにより層9は、約84重量%の亜鉛および16重量%のマグネシウムからなる。これらの層を作製するため、まず、7.5μmの亜鉛の層を電着により、1.5μmのマグネシウムの層を真空蒸着により堆積させ、金属薄板を熱処理してマグネシウムおよび亜鉛を合金にする。これらの試験片は、以下ZEMgと表す。
ZEMgおよびZnMgFullPVD試験片の基材3は、深絞り用冷間圧延鋼である。
試験片の一部は、17から20mg/m2の重量の硫黄を有する層13で被覆した。
−付与方法=スピンコーター(速度700RPM、15秒間)
−溶液濃度=硫酸亜鉛七水和物40g/L
−溶液pH=5
−溶液温度=周囲温度
−乾燥=試験片を70から80℃の間の温度にする。
−Quaker(登録商標)6130:油膜重量は約1g/m2と
−Fuchs(登録商標)4107S:油膜重量は約1.2g/m2。
−40℃±3℃、相対湿度約98%で8時間の第1の段階、および次に続く
−21℃±3℃、相対湿度98%未満で16時間の第2の段階、が含まれる。
−フランスの自動車メーカー向けに、Quaker6130オイル1g/m2で10サイクル後。
−ドイツの自動車メーカー向けに、Fuchs4107Sオイル1.2g/m2で15サイクル後。
この場合、金属薄板1の1種類の構成のみ検討した。被覆7には、厚さが約10μmのただ1つの層9が含まれ、約3重量%のマグネシウム、約3.7重量%のアルミニウムが含まれ、残りの部分は、亜鉛および避けられない不純物からなる。このとき、基材3は深絞り用冷間圧延鋼である。これらの試験片は、以下ZnMgAlと表す。
●:試験片(層13なし、塗油なし)
×:試験片(層13なし、ただし、Quaker6130油膜を約1g/m2の重量で塗油)
■:試験片(層13あり、Quaker6130油膜を約1g/m2の重量で塗油)
◆:試験片(層13あり、塗油なし)
