Abstract
A system is provided, comprising a two-sided adapter, made of a Ni-based alloy, that is connected at each of the two sides with a different type of metal, e.g. steel, and wherein the connection of the different types of metal, e.g. steel with the adapter is characterized in that it is achieved at least in part by use of friction welding. A method for linking different types of metal, e.g. steel by using a two-sided adapter as an intermediate, wherein at least one of the adapter-metal (e.g. steel) connections is made by means of friction welding, is also provided.
