A new concept of oxidation protection is proposed for Ni‐base alloys with Al‐amounts of 2–5 wt%. FollowingWagner'stheory of oxidation the formation of a dense protective alumina scale is possible if the Al‐activity is sufficiently high. This condition can be fulfilled by using the halogen effect. Thermodynamical calculations reveal the existence of regions for a positive effect of F and Cl for the alloys IN738 and IN939. In the case of fluorine these results are transformed into F concentrations in a screening by using ion implantation. By the F‐effect the oxidation mechanism at 1050 °C/air was changed from internal oxidation of Al to an external formation of an Al2O3– scale. Optimal implantation parameters were defined. The formation and stability of the protective alumina scale was proved within 1000 h/1050 °C.
