Abstract
Two types of steels were subjected to a nitro-carburized thermo-chemical treatment after thermo-magnetic treatments. The structural aspects into the superficial layer of these steels are studied during the friction process using an Amsler machine, taking two sliding degrees, different contact pressures and testing time. It was determined the durability of these materials, the surface structure evolution at different tests after thermo-magnetic treatments. The performed tests allowed to establish the influence of the thermal, magnetic and mechanical parameters on the behavior of these two steels taken for study during the friction process.
