Rezumat:

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 metalographic examinations, electronic microprobe investigations and hardness tests allow to appreciate yhe quality of the weldid joints. In the joining interface, the material enriched with carbon, nitrogen and axial diffusion were evidenced.
