    • ‘Although the actual chemical reactions taking place within a battery are very complex, the major cathodic and anodic reactions can be idealized based on a knowledge of the parts of a battery and their electrochemical function.’
    • ‘Welds made with these electrodes are cathodic to the base metal and thus resist galvanic corrosion.’
    • ‘There are three broad classes of corrosion-inhibiting admixtures, using different chemical mechanisms to control oxidation and the resulting corrosion - anodic inhibitors, cathodic inhibitors, and organic inhibitors.’
