to the invention l 21 vl 2 0 2 by weight zr 3 by weight fe is investigated in the three point bending test fig6 the plastic deflection can be increased significantly fracture only occurred under a force of approx 1 4 kn and the deflection of the specimen was approx 2 5 mm a further exemplary embodiment of the invention is illustrated in fig7 and 8 the comparison alloy vl 3 fractured under the action of a force of approx 2 kn with a deflection of 1 7 mm while the alloy according to the invention l 31 which differs from vl 3 in that it is additionally microalloyed with 3 by weight fe and 0 2 by weight zr presented deflection of approx 2 2 mm at the fracture point it was thus possible for the plastic deformation and therefore the ductility of the coating alloy to be increased significantly by the addition of these additional elements the fact that the nial phase was made more ductile makes the crack propagation slower i e the fracture toughness is increased which has a positive effect on the performance of the coatings under load naturally the invention is not limited to the exemplary embodiments described it can be applied to all coatings which contain u03b2 phase.
