Description
この溶射皮膜は、例えば、Cr−Fe合金粉末やステライト6(Co、Cr、Wの合金)粉末で、5〜60μmの粒度のものを用いて形成されている。
まず始めに、内周面に溶射皮膜1aが形成されたアルミニウム合金製容器1を、図1の模式図に示す通り、シリコンゴムでできた底蓋3で容器1の下端開口部を覆い、アルミニウム合金製容器1内部に濃度25%の苛性ソーダ水溶液11を収容・浸漬した後、50℃の温水5を満たした恒温水槽4内に配置した。次に、アルミニウム合金製容器1の上端開口部をガス取り込み口12を有する上蓋2で密封し、ガス取り込み口12からチューブ6を経由して常温の水8で満たした水槽7内に立設したビレット9に水素ガス10を収集した。
R=a・T1/2+b
ここで、R:電池抵抗、a:劣化係数(防食皮膜の性能によって変化する)、T:時間、b:初期抵抗。
表1のデータは各水素ガス量品質水準の皮膜でコーティングされたアルミニウム合金製容器で作られたNAS電池を6ヶ月間運転し、その期間の抵抗増加データをもとに係数aを各水素ガス量品質の水準ごとに求め、それを標準の係数で除した値を抵抗増加率として示している。
