Abstract
The cylindrical pore structure and barrier layer of anodic films forme d on magnesium which are similar to the Keller's model of anodic alumi na are determined by direct cross-sectional observation. The ratios of cell diameter and barrier layer thickness to the forming voltage are notably smaller than those associated with anodic alumina. It is assum ed that anodic film growth proceeds mainly by the formation of MgF2 an d Mgx+y/2Ox(OH)(y) (magnesium oxyhydroxide) at the metal/film interfac e and the dissolution of the film at pore bases.
