Abstract
Description
剥離する工程(304)の後、剥離された7xxxアルミニウム合金製品(200)上に官能層を作製することができる。官能層を作製する前に、剥離済7xxxアルミニウム合金製品(200)を、例えば剥離済7xxxアルミニウム合金製品(200)をすすぐことによってさらに調製することができる。このすすぎは、デブリおよび/または残留化学物質を除去するために水(例えば、脱イオン水)ですすぐことを含むことができる。一実施形態において、すすぐ工程は、剥離済7xxxアルミニウム合金製品(200)の表面上にさらなる酸化アルミニウムを成長させ、それは、調製された表面酸化層の厚さを名目上増加させることができる。
上述のように、7xxxアルミニウム合金を使用して、本発明の様々な発明的な態様を説明したが、本明細書に記載の方法は、任意のマグネシウム含有アルミニウム合金に仕様してもよい。マグネシウム含有アルミニウム合金は、上述のMgO層が形成されうるように、十分量のマグネシウムを有するアルミニウム合金である。非限定的な例として、マグネシウム含有アルミニウム合金は、0.2~6重量%Mgを含む。一実施形態において、マグネシウム含有アルミニウム合金は、少なくとも0.5重量%Mgを含む。実際に、本開示は7xxxアルミニウム合金製品およびその金属間粒子の剥離に関して説明してきたが、本明細書に記載の剥離技術は、剥離用に利用可能な金属間粒子を有する他のアルミニウム合金にも適用可能であることが予想される。そのようなその他のアルミニウム合金は、2xxx、5xxx、6xxx、および8xxx(例えば、高量の鉄またはリチウムを含む8xxxアルミニウム合金)のうちの1つ以上を含みうる。
本明細書で提供されるテンパーおよびアルミニウム合金の定義(2xxx、5xxx、6xxx、7xxx、8xxx)は、ANSI H35.1(2009)に従う。
本明細書に開示されるシステムおよび方法は、7xxxアルミニウム合金製品、例えば銅含有金属間化合物粒子の形成をもたらす銅を含むものに適用可能でありうる。1つの方法では、7xxxアルミニウム合金製品は2~12重量%のZn、1~3重量%のMg、および1~3重量%のCuを含む。一実施形態において、7xxxアルミニウム合金製品は、Aluminum Association Teal Sheets(2015)によって規定される、7009、7010、7012、7014、7016、7116、7032、7033、7034、7036、7136、7037、7040、7140、7042、7049、7149、7249、7349、7449、7050、7150、7055、7155、7255、7056、7060、7064、7065、7068、7168、7075、7175、7475、7178、7278、7081、7181、7085、7185、7090、7093、7095、7099、または7199アルミニウム合金のうちの1つである。一実施形態において、7xxxアルミニウム合金は7075、7175、または7475である。一実施形態において、7xxxアルミニウム合金は7055、7155、または7225である。一実施形態において、7xxxアルミニウム合金は7065である。一実施形態において、7xxxアルミニウム合金は7085または7185である。一実施形態において、7xxxアルミニウム合金は7050または7150である。一実施形態において、7xxxアルミニウム合金は7040または7140である。一実施形態において、7xxxアルミニウム合金は7081または7181である。一実施形態において、7xxxアルミニウム合金は7178である。剥離前は、7xxxアルミニウム合金製品は、Fテンパー、Wテンパー、またはTテンパーのいずれでもよい。7xxxアルミニウム合金製品で剥離されうる金属間粒子の非限定的な例としては、例えばAl7Cu2Fe、Al2CuMg、Al12(Fe,Mn)3SiおよびAl6(Fe,Mn)粒子などの成分粒子(例えば、固化中に形成される不溶性相など)が挙げられる。剥離されない場合がある強化相の非限定的な例は、特に、Mg2SiおよびMg2Znの析出物であり、Al3Zr、Al12Mg2Cr、Al12(Fe,Mn)3Si、およびAl20Cu2Mn3の分散質(例えば、均質化中に形成された粒子)である。
本明細書に開示されるシステムおよび方法は、6xxxアルミニウム合金製品に適用可能である。1つの方法では、6xxxアルミニウム合金製品は0.2~2.0重量%のMgと、0.2~1.5重量%のSiと、最大1.0重量%のCuを含む。一実施形態において、6xxxアルミニウム合金製品は、特に6111、6013、6022、6x61、6082、6014、6016、または6063アルミニウム合金製品のうちの1つである。剥離前は、6xxxアルミニウム合金製品は、Fテンパー、Wテンパー、またはTテンパーのいずれでもよい。6xxxアルミニウム合金製品において剥離されうる金属間粒子の非限定的な例としては、特に、例えばAl12(Fe,Mn,Cr)3SiおよびAl9Fe2Si2が挙げられる。剥離されない場合がある強化相の非限定的な例は、特にMg2SiおよびQ相(Al5Cu2Mg8Si6)析出物がある。
本明細書に開示されるシステムおよび方法は、5xxxアルミニウム合金製品に適用可能である。1つの方法では、5xxxアルミニウム合金製品は0.5~6.0重量%Mgである。一実施形態において、5xxxアルミニウム合金製品は、特に5754、5182、5052、5050、5083、5086、5154、5252、5254、5454、5456、5457、5652、5657、5349、5005、または5022アルミニウム合金製品のうちの1つである。剥離前は、5xxxアルミニウム合金製品は、OテンパーまたはHテンパーのいずれでもよい。5xxxアルミニウム合金製品において剥離されうる金属間粒子の非限定的な例としては、例えば特にAl12(Fe,Mn)3Siが挙げられる。
本明細書に開示されるシステムおよび方法は、2xxxアルミニウム合金製品に適用可能である。1つの方法では、6xxxアルミニウム合金製品は0.5~7重量%のCuと、0.2~2.0重量%のMgを含む。一実施形態において、2xxxアルミニウム合金製品は、特に、2024、2014、2124、2090、2011、または2219アルミニウム合金製品のうちの1つである。剥離前は、2xxxアルミニウム合金製品は、Fテンパー、Wテンパー、またはTテンパーのいずれでもよい。2xxxアルミニウム合金製品において剥離されうる金属間粒子の非限定的な例としては、例えば特にAl7Cu2Fe、Al2Cu、Al2CuMg、Al12(Fe,Mn)3Si、Al6(Fe,Mn)、およびAl20Cu2Mn3が挙げられる。剥離されない場合がある強化相の非限定的な例は、特にAl2Cu、Al2CuMg、Al2CuLi、およびAl3Liである。
7xxxアルミニウム合金シート製品(Al-Zn-Mg-Cu型)を製造し、T76テンパー(ANSI H35.1要件による)に加工した。7xxxアルミニウム合金シートから試料を採取し、その後、試料の外表面を有機溶媒(例えば、ヘキサン)で洗浄した。次いで、試料を、300W定格電力を有するパルス型レーザーユニットであるNd:YAGレーザー(Adapt LaserモデルCL300)に露光した。試料を処理するために使用されるパルス持続時間は、80~200nsで変化させた。390μmのビーム径を処理に使用した。一部の試料を35kHzの第一のパルス周波数条件(1)に晒し、その他の試料は25kHzの第二のパルス周波数条件(2)に晒した。
典型的な未処理の7xxx金属表面は、図8f(図8eと同じ倍率)、および後方散乱型電子(BSE)モードのSEMで示されている。画像は、比較的滑らかな表面上のFeおよびCuを含む明るい成分粒子を示す。粒子は一般的に、直径が10マイクロメートルより小さく、圧延方向に整列しており、クラスターの形態であることが多い。剥離ピットおよびしわは一般的には存在しない。
7xxxアルミニウム合金製品のいくつかの試料は、Yb-YAGレーザーを使用して剥離された。レーザー条件は、実施例1と類似したものであった。レーザー剥離後、試料をSEMによって調べた。SEM分析により、Yb-YAGレーザーが表面から金属間粒子を適切に剥離し、実施例1に記述された特徴的な剥離ピットを後に残したことを確認した。試料に表面溶融の兆候はなかった。
実施例2のレーザー剥離された試料の一部は、レーザー剥離の後に接着接合されたが、官能化されることなく、すなわち、官能化層が試料に追加されなかった。その後、実施例1および2に従って、試料を同じ業界標準の周期的腐食曝露試験に供した。12の試料のほぼすべてが試験に失敗し、多くは30サイクル以内に失敗した。したがって、レーザー剥離単独では、接着接合に適した7xxxアルミニウム合金製品の製造が容易にならないようである。官能化ステップ/官能化層が必要なようである。
実施例2のレーザー剥離された試料の一部は、接合前に希釈酸溶液による化学的エッチングによって接着接合のための調整がされたが、官能化はなされず、すなわち官能化層は試料に加えられなかった。その後、実施例1および2に従って、試料を同じ業界標準の周期的腐食曝露試験に供した。8つの試料のすべてが19サイクル以内に試験に失敗した。したがって、酸化物エッチングは、官能化処理の適切な代用ではない。
