Cathodic and anodic reactions of corrosion were inhibited simultaneously 極化曲線測試表明,低磷配方是一種混合型緩蝕劑。
The electrochemical impedance spectroscopy of anodic reaction shows that the formation of black nickel was mainly controlled by electrochemical reaction at low anodic potential , and is mainly controlled by electrochemical reaction and diffusion at high anodic potental . with the increasing of anodic potential . , the formation of black nickel is still controlled by electrochemical re 陽極反應的電化學阻抗譜表明,氧化電位較低時ni ( oh ) :氧化生成黑鎳的過程主要受電化學反應所控制,電位較高時,黑鎳形成過程主要受電化學反應及擴散混合控制,電位進一步增加,析氮反應占據(jù)主導優(yōu)勢,陽極氧化過程仍主要受電化學反應及擴散混合控制。
