    Abstract: 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.

    Abstract translation: 公开了一种保护层,其具有组合物为1.5%至2.5%的铼,11%至13%的钴,20%至22%的铬,10.5%至11.5%的铝,0.3%至0.5%的钇和或至少一种当量的金属 来自包括钪和稀土的组,其余由镍组成。 现有的保护层具有高的Al和/或Cr含量,并且通过重新形成脆性相进一步增强,在脆性相中,在使用中另外在碳的影响下脆化。 本发明几乎不显示Cr / Re沉积的脆性。
