Friction Welding Method and Components Produced From Steel and Metal Aluminide Using an Intermediary From an Ni Alloy

摘要

A method for connecting a first component from a metal aluminide or a refractory Ti alloy to a second component from steel, metal aluminide or a refractory Ti alloy, especially from a steel shaft, by friction welding is disclosed. An intermediary from an Ni alloy is inserted between the first component and the second component and friction welding is carried out. A connecting layer is produced from the intermediary and is firmly connected on both ends to the first and the second component. A turbocharger rotors and valves for internal combustion engines produced by the disclosed method is also provided.
