In thispresentation, surface treatment of light metals, such as aluminum, magnesium and titanium, based on electrochemical methods will be introduced. Anodic and cathodic methods used to modify the surface characteristics of light metals are being introduced and explained in view of a number of factors of the form of applied current, applied voltage, ionic migration, dissolution or dielectric breakdown of anodic oxide films, arc generation and anodic film growth under the application of high anodic electric field in electrolytes. The effects of alloy composition and electrolyte composition on the formation and growth of anodic films on light metals will be also mentioned based on in-situ observation of arcs, voltage-time curves, and morphological observation of the PEO (Plasma Electrolytic Oxidation) films.
