Description
前記ハウジングはアルミニウム合金からなり前記シャフトを固定する固定部をもち、
前記シャフトは表面に窒化層をもつステンレス鋼からなり、前記固定部と電気的に接触することで該固定部から防食電流を供給される短絡部と、該短絡部から延出し外周面に炭素を主成分とし珪素を含む非晶質炭素膜が被覆されてなり前記ロータを枢支する枢支部と、をもつことを特徴とする。
上記実施例で用いたSUS304窒化材およびADC12の自然浸漬電位を測定した。なお、SUS304窒化材は、530℃で1時間、SUS304の棒状体の全体をプラズマ窒化処理することで、棒状体の表面に23μmの窒化層を形成して得た。SUS304窒化材またはADC12を用いて作製した試料電極と、銀/塩化銀からなる参照電極と、を試験液(NaCl水溶液または水道水)を満たした容器内に順に挿入し、この状態で、試料電極と参照電極との間の電位差ΔE(自然浸漬電位)を電位計で測定した。測定中、試験液の温度を80℃とした。また、NaCl水溶液(試験液)としてNaCl濃度が5質量%、1.2g/Lの二種類について行った。測定結果を図3に示す。
