Abstract
Using pulsed current and relatively low average voltages, articles containing light metals such as magnesium may be rapidly anodized to form protective surface coatings. The anodizing solutions employed may contain phosphate, permanganate, silicate, zirconate, vanadate, titanate, hydroxide, alkali metal fluoride and/or complex fluoride, optionally with other components present.
