Abstract: A method is provided for reducing the corrosion rate of surfaces of formed magnesium or magnesium alloy articles in which the formed surface contains small embedded particles of iron. By exposing the iron particle-containing formed surface to an acidic, aqueous solution comprising alkali metal fluoride ions at a temperature of between 20° C. and 30° C., an adherent passivating layer of MgF2 is formed. Further, such exposure to the acidified, aqueous, fluoride ion-containing solution reduces or eliminates the concentration of cathodic, corrosion-promoting, iron-containing particles on the article surface as the magnesium fluoride layer is being formed. The development of the passivating layer reduces corrosion in a water-containing environment, and even if the passivating MgF2 layer is breached, the reduction in surface iron-containing particles reduces the inherent corrosion rate of the article.
