The paper analyzes the characteristic features of building up joinings by friction welding between carburized and nitrided steels having a carbon or nitrogen concentration gradient in the cross section. The metallographic examinations, electronic microprobe investigations and hardness tests allow to appreciate the quality of the welded joints. In the joining interface, the material enriched with carbon, nitrogen and axial diffusion were evidenced.
