<p>The alloy composition, expressed in wt%, is as follows. Nickel 27-31, chromium 23-29, aluminum 7-11, SE 0.5-0.7, silicon 0.6-0.8, zirconium 0.5-0.7 and cobalt to 100%; where SE is yttrium and/or at least one metal selected from scandium and the rare earth elements. A variety of variant compositions based on the foregoing are included. In addition to this protective alloy layer (7), an additional thermal insulation layer (10) is applied. A substrate (4) of the component is nickel- and/or cobalt based.</p> |
