Some 38MoCrAl09 (SAE 4038) steel grade samples were subjected to plasma nitriding treatment regimes. The structural and diffractometric aspects of the superficial layers of the steel are studied after the wear tests by friction, using an Amsler type machine, taking two sliding degrees at different contact pressures and testing time. The tests were made to detect the sustainability to the material, the evolution of the superficial layer through different tests and to establish the influence of these tribological factors (operating parameters) on the superficial layers.
