Abstract

This paper aim to be considered a review of the own researches realized in the non-conventional treatments domain in the magnetic field. The magnetic field applied under certain conditions, during the cooling process of the steel samples in the case of the improvement treatments, modifies the mechanical properties of the steel.It is important to take in consideration the improvement of the mechanical properties of a Cr-Mo alloyed steel used for the construction of the industrial machines parts. In this case, the influence of the magnetic field applied during the improvement treatment on the mechanical properties was considered. A thermo-chemical treatment in plasma completed the treatment program. The structural changes in the superficial layers during the treatment determine the improvement of the mechanical properties of the steel tested during the wear process.The tribo-models behavior during the dry friction processes was analyzed. This study determines the wear intensity for a certain type of tribo-model and for a certain type of material. An Amsler stand was used for all wear tests. The rollers with different diameters were used in order to obtain different sliding degrees (ξ) and two distinct values of task of loading (Q) were considered.

Keywords: Steel, non-conventional treatment, wear process, mechanical properties.
