Beschreibung
Zusammenfassung:	The invention relates to a method for producing a turbine rotor (1) of an exhaust gas turbocharger, wherein the turbine rotor (1) comprises a turbine wheel (2) with a hub (4) and turbine blades (5) that extend from the hub (4), and a shaft (3), said method comprising the steps of: providing the turbine wheel (2) and the shaft (3); forming a protective layer by applying or introducing a halogen on or in the surface of the turbine wheel (2) and subsequently heat-treating the turbine wheel (2); and connecting the shaft (3) to the hub (4) of the turbine wheel (2). The invention further relates to the use of a turbine rotor (1).
