摘要:
A two-ply MCrAlX layer is provided. The two-ply MCrAlX layer includes nickel and cobalt, but also Cr, Al and Y, differ significantly, in order to improve both oxidation resistance and thermal-mechanical strength. A layer system including a substrate and the two-ply MCrAlX layer is also provided. The MCrAlX layer includes an inner layer and an outer layer.
