ABSTRACT:
Protective layers of the MCrAlX type according to the prior art are often provided with a platinum layer to prevent diffusion of elements out of the base material into the MCrAlX. The MCrAlX alloy according to the invention includes halogens (F, Cl, Br, I), which prevent this diffusion, in particular of titanium.
