anodic passivationとは 意味・読み方・使い方

Passive films are formed on a surface of chrome plated layer on the opening side end of a piston and inside a micro crack formed by a passivation process in which an anodic oxidation coating layer is formed on the surface of a piston base body made of aluminum alloy and a chrome plated layer is formed on the anodic oxidation coating layer to be immersed in nitric acid solution.例文帳に追加

アルミニウム合金製のピストン基体の表面に陽極酸化皮膜層を形成し、該陽極酸化皮膜層上にクロムめっき層を形成した後、硝酸溶液に浸漬する、不動態化処理によりピストンの開口側端面のクロムめっき層の表面およびマイクロクラックの内部に不動態皮膜を形成する。 - 特許庁

To provide an electrolytic method of preventing anodic passivation by eliminating any high concentration area of metal subjected to electrolysis such as copper which is locally or globally generated in the vicinity of an anode surface to unify the whole concentration distribution between both electrode plates for the electrolyte between anodes and cathodes, and to provide an electrolytic tank used therefor.例文帳に追加

アノード及びカソード間の電解液について、特にアノード表面近傍に局所的あるいは全体的に発生する銅等電解目的金属の高濃度領域を解消し、両極板間全体の濃度分布を均質化してアノードの不働態化を防止する電解方法、及びこれに使用する電解槽の提供。 - 特許庁
