Claim:
1. A method for depositing at least one layer of material on a workpiece made of a material including a titanium aluminide, the method comprising the steps of: heating the workpiece in a localized region by induction to a predefined preheating temperature, the heating creating a heated surface of the workpiece; depositing an additive including the titanium aluminide on the heated surface of the workpiece by build-up welding, wherein the deposition step includes the steps of depositing the additive in powder form on the surface of the workpiece and melting the deposited additive by a laser beam or a plasma jet; and cooling the workpiece at a defined cooling rate to a cooling temperature, the cooling temperature being between 500° C. and 650° C., the defined cooling rate being between 5 K/min and 50 K/min.
