Abstract
An adhesion promoter layer is produced by a novel composition with a lower cobalt content in an MCrAlY alloy. The adhesion promoter layer leads to a very slow growth of the TGO. The nickel-based alloy contains at least (in wt. %): cobalt (Co) 0.2%-5.0%, chromium (Cr) 14.0%-20.0%; aluminum (Al) 6.0%-8.0%; tantalum (Ta) 1.0%-3.0%; yttrium (Y) 0.3%-0.6%; nickel (Ni) 70.0%-75.0%.
