Process for obtaining a mechanical component

摘要

A process for obtaining a mechanical component by joining a first metallic material and a second metallic material. The process comprises: (A) putting the first material and the second material in contact with each other, (B) fixating a sheet metal element onto the first material to at least partly enclosing the second material and so that the sheet metal element is at least partly in contact with the second material. The sheet metal element comprises carbon, joining the first material and the second material by diffusion welding. The carbon activity of the second material Ca2 and the carbon activity of the sheet metal element Cam at the temperature of joining fulfills a relation Ca2≦Cam.
