摘要：

A simplified physical model of inhomogeneous aluminum oxide layers, including the formation of passive and active pits is developed in order to explain experimental impedance data of technical samples prepared under different formation and sealing conditions. Moreover, aging and corrosion effects after long time exposure in different climate are studied and compared with model simulations and experiments under artificial corrosion conditions.
