Description
I.表面酸化物の厚さを減少させること
A.化学的調製
i.アルカリ調製溶液
ii.酸調製溶液
B.機械的調製
II.7xxxアルミニウム合金
III.官能化層の形成
7xxxアルミニウム合金シート(7075−T6)を未処理状態で、様々な試料に切断した。図8は、典型的な未処理の酸化物を示す。未処理の酸化物の厚さおよび組成を、XPS(X線光電子分光法)により測定し、その結果を以下の図4a〜4bに示す。これらの7075−T6試料の表面を溶剤(例えば、ヘキサンまたはアセトン)で拭くことにより調製し、有機汚染物質および汚れを除去した。続いて、希釈したBONDERITE 4215 NC溶液と140°Fで2分間接触させた。この調製により、試料の酸化物厚さは減少した。図5a〜5bに示すように、一試料では、酸化マグネシウムの含有量の実質的な減少(10at%Mg未満に)と共に、酸化物の厚さは11nm未満に減少した。次に、試料を2分間水道水でリンスすることにより、水切れがないことが分かり、有機汚染物や汚れが十分に除去されていることを示す。次に試料を有機リン含有酸で150°Fで8秒間処理してその上に官能化層を生成した。図6a〜6bは、官能化層を上に有する一つの試料のXPS測定を例示する。例示のように、酸化物の組成および厚さは変化しないままであり、正味の効果は酸の酸化物層内への意図された浸透であり、これはリン(P)の存在によって8nmの深さまでであることを示した。酸化マグネシウムを除去することにより、この浸透が促進する。
