Disclosed is a protective layer having the composition 1.5% to 2.5% rhenium, 11% to 13% cobalt, 20% to 22% chrome, 10.5% to 11.5% aluminum, 0.3% to 0.5% yttrium and or at least one equivalent metal selected from the group comprising scandium and the rare earths and the remainder consists of nickel. Existing protective layers which have a high Al and/or Cr content and which are additionally reinforced by Re-forming brittle phases that, during use, additionally embrittle under the influence of carbon. The present invention hardly exhibits a brittleness by Cr/Re depositions.
