Known protective layers with a high Cr content and in addition silicon form brittle phases which additionally embrittle during use under the influence of carbon. The protective layer according to the invention has the composition of from 24% to 26% cobalt (Co), from 10% to 12% aluminium (Al), from 0.2% to 0.5% yttrium (Y), from 12% to 14% chromium (Cr), from 0.3% to 5.0% tantalum (Ta), nickel (Ni). |
