FRICTION WELDING METHOD AND COMPONENTS PRODUCED FROM STEEL AND METAL ALUMINIDE USING AN INTERMEDIARY FROM AN NI ALLOY

摘要

The invention relates to a method for connecting a first component (1, 3) from a metal aluminide or a refractory Ti alloy to a second component (2) from steel, metal aluminide or a refractory Ti alloy, especially from a steel shaft, by friction welding. According to said method, an intermediary (4) from an Ni alloy is inserted between the first component (1, 3) and the second component (2) and friction welding is carried out. A connecting layer (4) is produced from the intermediary (4) and is firmly connected on both ends to the first (1, 3) and the second component (2). The invention also relates to turbocharger rotors and valves for internal combustion engines produced by said method.
