Abstract
The present invention relates to a diffusion welding assembly process between a martensitic stainless steel and a copper alloy, and in particular, to an assembly process of a martensitic stainless steel component with a component comprising copper. Said process may be used for example to produce a bimetal part designed to operate at high temperatures. It particularly comprises a step consisting of degreasing and stripping the surfaces of the components to be assembled, a step consisting of placing the degreased and stripped surfaces of the components to be assembled in direct contact and a step consisting of diffusion welding assembly.
