A method for producing oxidic protective layers by the treatment of metallic surface in an oxidizing atmosphere in which the O2 pressure or partial pressure of the treatment medium, governing the oxidation potential as it does, is continuously varied during the oxidation process to control the nucleation and growth rate of the oxide being produced. The O2 supply of the treatment medium, which is continuously varied in the course of oxidation, results in a dense, isotropic structure of the resultant oxide layer with a minimum of defect concentration. |
