摘要：
In this paper is revealed the structural transformations and diffusion processes that take place as a result of the local thermo-mechanical treatment regimes specific to friction welding of nitrided and not nitrided quenched and tempered steels. To obtain welded joints with good mechanical properties it is necessary to remove the nitrided layer from the contact surfaces.
