ABSTRACT:
A method for producing protecting layers on a metal selected from aluminum, titanium and zirconium, or alloys thereof, involves at least two anodic oxidation steps producing oxide layers and a thermal treatment which is carried out before or simultaneously with last anodic oxidation step. The treated metal according to the invention is protected even at high temperatures and under conditions of thermal cycling.
