Abstract (en)
[origin: WO2014005906A1] The invention relates to a method (100) for connecting a turbine wheel (300) to an intermediate piece (302) at a joint, wherein the method (100) comprises a provision step (102), an arrangement step (104), and a temperature control step (106). In the provision step (102), the turbine wheel (300) and the intermediate piece (302) are provided, wherein the turbine wheel (300) is made of a first material and has a first contact surface, and the intermediate piece (302) is made of a second material and has a second contact surface, wherein the first material and the second material are different. In the arrangement step (104), the intermediate piece (302) is arranged in a position relative to the turbine wheel (300), wherein the second contact surface is arranged facing the first contact surface in the area of the joint. In the temperature control step (106), the turbine wheel (300) and the intermediate piece (302) are brought to a sintering temperature, wherein the turbine wheel (300) and/or the intermediate piece (302) is sintered in order to connect the first contact surface and the second contact surface at the joint.
