Abstract

Protective layers, according to the prior art, achieve their protective function b depletion of a defined element that forms a protective oxide layer or that is exhausted as a sacrificial material. Once said material is exhausted, the protective function cannot be maintained. The invention is characterized by using particles (1) that contain a sustained-release depot of the exhaustible material. For this purpose, the material is present in a superstoichiometric form.
