Description
)、チタン系(TiFeなど)、マグネシウム系(Mg2Niなど)、バナジウム系(V
)、またはレアメタルの混合体であるミッシュメタル−Ni系等の使用が可能である。
ュメタル−Ni系の水素吸蔵合金とはLa−Ni系水素吸蔵合金のLa部分をミッシュメタル(Mm)で置換したものである。La−Ni系水素吸蔵合金は、水素吸蔵合金としては優れた特性を有しているが合金がやや高価であるという欠点を有する。
初回測定において約400Kにおいて観測される上向きのピークは水素吸蔵開始(活性化)反応に起因することが知られている。図5の高速フレーム(HVOF)溶射により作製した水素吸蔵合金皮膜(b)は原料粉末(a)と比較して、活性化ピークが低温度側にシフトしており活性化反応が起こりやすくなっている。
成−温度(PCT)曲線を示したものである。図6における水素吸蔵合金皮膜(b)は原料粉末(a)に比べて任意の平衡圧力における水素吸蔵量は約半分になっているが、曲線の形状は類似しており、水素吸蔵・放出に関する反応機構は原料粉末と同様と推測される。
Claims (1)
- ミッシュメタル―Ni系水素吸蔵合金粉末と前記水素吸蔵合金より熱伝導が良好な金属粉末とが、燃焼ガスが不活性ガスで希釈された高速フレームにより非溶融の状態で基板上に溶射され、形成されてなることを特徴とする熱伝導性が良好な多孔質の水素吸蔵合金溶射皮膜。
