Abstract

The invention relates to a coating which contains large volumetric fractions, preferably from 20 to 90% by volume, of NiAl-&bgr; phase in a &ggr; matrix. It contains the following microalloying elements which increase the ductility of the coating (data in % by weight): 0.1-8 Fe and/or 0.1-8 Mo and/or 0.1-8 Ga, where the total Fe, Mo and Ga content is at most 10%. In addition, small amounts of Zr, C and/or B may be added to the alloy, strengthening the &bgr;/&ggr; phase boundaries.
