Description
本願は、2018年3月9日に提出された米国特許出願62/641223の利益を主張する。当該特許出願は、本願に引用された他の全ての参考文献と共に参照として本願に組み込まれる。
本発明は、材料の分野に関し、より具体的には、銅ニッケル合金発泡体およびその作製に関する。
新規な作製方法によって、5つの異なる組成を有する3次元(3−D)結合銅ニッケル合金発泡体が、凍結成形(freeze casting)を用いて首尾よく作製され、様々な気孔率(約55%〜約75%)の開口気孔構造を有する。これらの合金発泡体は、改良された機械特性を有すると共に、対照物よりも高い比表面積および高い透過性を有することができる。この新種材料は、改良された機械特性および腐食特性を示し、様々な構造用途(例えば、高温構造材料)および機能用途(例えば、フィルタおよびエネルギー材料)に使用することができる。
多孔質発泡体構造体の作製は、以下のステップ、すなわち、(a)ポリビニルアルコール結合剤(PVA結合剤)および水とを混合したニッケル酸化物および銅酸化物粉末混合物のスラリーを調製するステップ、(b)分散剤としてDarvan811(低分子量のポリアクリル酸ナトリウム粉末分散剤)を添加するステップ、(c)スラリーを約30分間撹拌し、その後約1時間超音波処理することによって分散させるステップ、(d)粉末スラリーを鋳型に配置し、銅棒の低温表面と接触することによって凍結するステップ、(e)凍結スラリーを減圧低温で昇華させることによって、多孔質CuO−NiO発泡体生地を形成するステップ、(f)多孔質CuO−NiO発泡体生地を約250〜300℃の低温で焼結および窒化し、その後その温度で約2〜3時間保持することによって、結合剤を除去し、酸化物を還元した後、5%アルゴンおよび水素ガス混合物の下で、約800℃〜約1000℃の高温で約3時間〜約8時間焼結することによって、銅ニッケル合金発泡体を形成するステップを含む。
図3は、発泡体のニッケル含有量に対するXRDによって決定された格子定数の変化を示す図である。
図8は、約70〜80℃で30日間、希釈H2SO4溶液(pH=1)の静止硫酸環境に保持した場合、時間の経過に伴う重量の減少の関数として、Cu発泡体、Cu3Ni7発泡体、Cu5Ni5発泡体、Cu7Ni3発泡体、およびニッケル発泡体の耐食性の比較を示す図である。グラフの隣りの数値は、合金発泡体の気孔率を表す。
ニッケル酸化物粉末(約20nm未満の平均粒径を有するNiO)および銅酸化物粉末(約40nm〜約80nmの粒径を有するCuO)を用いて、銅ニッケル合金発泡体を作製する。まず、3重量%のポリビニルアルコール結合剤(分子量約89000〜98000g/molのPVA結合剤)と蒸留水との混合物を調製し、その後80℃まで加熱して結合剤を溶解する。次に、様々な重量比の銅およびニッケル粉末を調製溶液に懸濁させることによって、様々な組成の銅ニッケルスラリーを形成する。懸濁液の安定性を高めるために、分散剤として、0.09gのDarvan811(低分子量ポリアクリル酸ナトリウム粉末分散剤)を添加する。次に、スラリー溶液を約30分間撹拌して、その後約1時間超音波処理することによって分散させる。粒子を十分に分散させるために、このプロセスを2回に繰り返す。
多孔質CuO−NiOから銅ニッケル合金発泡体への完全変換を確認するために、X線粉末回折(XRD)分析を行った。図1は、5%アルゴンおよび水素ガス雰囲気下で箱型加熱炉において同時還元もしくは焼結またはその両方を行う前の調製されたCuO−NiO発泡体生地と、5%アルゴンおよび水素ガス雰囲気下で箱型加熱炉において同時還元もしくは焼結またはその両方を行った後の合成銅ニッケル合金発泡体とのXRDパターンを比較する。最終の合成銅ニッケル合金発泡体のXRDパターンから分かるように、XRDパターンは、高温固溶合金化メカニズム(図2)に基づいて、出発CuO−NiO粉末が銅ニッケル相の組み合わせに完全に変換されたことを確認した。
