Abstract
Description
Biが添加されているAl複合材料(例えば、Al−1wt%Bi)からなるAl合金溶射膜は、Al中にBiが均一に高度に分散しているので、水、水蒸気、水溶液等のような水分の存在する雰囲気中(例えば、80℃)で容易に反応して溶解する。Biは反応サイト数に影響がある。しかし、溶射後10時間、大気中に放置すると、大気中の水分と容易に反応し、粉化現象が発生するというデメリットがあるため、以下述べるように、溶射膜形成後に安定性を得るためにSiを添加することが必要になる。
Al、Bi、Si、Ti、Ce及びMgを用意し、Alに対して、Al重量基準で、0.2wt%以上2wt%以下、好ましくは0.5wt%以上2wt%以下のBi、1.5wt%以上8wt%以下のSi、0.2wt%以上4wt%以下のTi、0.2wt%以上2wt%以下のCe、及び0.2wt%以上2wt%以下のMgを配合し、Al中に各金属を均一に溶融させた後、ロッド又はワイヤー形状に加工した物を溶射材料として用い、例えばワイヤー式フレーム溶射法により、成膜装置の防着板等の成膜室用構成部材のような基材の表面に吹き付けて急冷凝固させ、被覆することにより所望の水反応性Al合金溶射膜を備えた基材を製造することができる。かくして得られたAl合金溶射膜は、上記したように、Al結晶粒中にBiが均一に高度に分散した状態で存在している膜である。
(参考例1)
Al、Bi、Si、及びTiを用い、また、さらにCeを添加し、以下の組成におけるCe添加による溶射膜の剥離時間(時)に対する影響を検討した。添加量は、Al重量基準である。対照として、ワイヤー式フレーム溶射により得られたAl−In系のAl−3wt%In−0.4wt%Si−0.2wt%Ti(特許第5517371号公報参照)を用いた。
・Al−1wt%Bi−3wt%Si−1wt%Ti(N数:3)
・Al−1wt%Bi−3wt%Si−2wt%Ti(N数:3)
・Al−1wt%Bi−3wt%Si−1wt%Ti−0.2%Ce(N数:3)
・Al−1wt%Bi−4wt%Si−1wt%Ti(N数:3)
・Al−1wt%Bi−4wt%Si−2wt%Ti(N数:3)
参考例1の記載に従って得られた各組成からなる各Al合金溶射膜(擬似デポ膜)に対する熱処理(250℃×100)の代わりに、本参考例では、270℃の熱処理(大気中、150時間、炉冷)を施して、参考例1のプロセスを実施した。熱処理を経た後の溶射膜付基材を80±1℃の純水300ml中に浸漬し、各溶射膜(擬似デポ膜)の剥離時間(時)を測定し、溶解性を検討した。得られた結果を、図2に示す。図2において、縦軸は擬似デポ膜剥離時間(hr)である。
・Al−1wt%Bi−3wt%Si−1wt%Ti−0.2wt%Ce−0.5wt%Mg(N数:3)
・Al−1wt%Bi−3wt%Si−1wt%Ti−0.2wt%Ce−0.5wt%Mg(熱処理:未処理、N数:3)
・Al−1wt%Bi−3wt%Si−1wt%Ti−0.2wt%Ce−0.5wt%Mg(熱処理:200℃×150hr、N数:3)
・Al−1wt%Bi−3wt%Si−1wt%Ti−0.2wt%Ce−0.5wt%Mg(熱処理:250℃×150hr、N数:3)
・Al−1wt%Bi−3wt%Si−1wt%Ti−0.2wt%Ce−0.5wt%Mg(熱処理:300℃×150hr、N数:3)
