Title:
摩擦溶接方法及びニッケル合金製の中間接合部分を用いた鋼及び金属アルミナイド製の構成要素
Document Type and Number:
Japanese Patent JP2008534288
Kind Code:
A
Abstract:
The method for the connecting of a first component (1,3) of a metal aluminide or a high melting point Ti-alloy to a second component (2) of steel, metal aluminide, or high melting point Ti-alloy entails introducing an intermediate piece (4) of a Ni-alloy between the first and second component and then carrying out a friction welding process. A connecting layer is formed from the intermediate piece and is rigidly connected on both sides to the first and respective second component. Independent claims are included for the following: (A) a turbocharger rotor with a turbine wheel (1), steel shaft (2), and a compressor wheel (3), whereby the turbine wheel and/or the compressor wheel are formed from metal aluminide and connected to the shaft via a connecting layer of Ni-alloy; and (B) a valve for internal combustion engines with a valve plate of metal aluminide connected to a steel stem via a connecting layer.
