Cathodic modification withinchemistry is the retardation ofanodic reaction as the result of an increase in the ability of analloy to be passivated by the introduction of an activecathode into the alloy e.g. the alloying ofstainless steel andtitanium withplatinum group metals(1). This is one way in whichcorrosion resistant alloys can be produced and the resistance of alloy against electrochemical attack increased.
