The paper wants to be a review of the own researches realized in the nonconventional treatments domain, corresponding to the magnetic field treatments applied to a steel of construction for industrial parts, for gears and some parts of industrial machines. The magnetic field applied under certain conditions during the cooling process of the sample in the case of the improvement treatments, modifies the properties of steel, the hardness, the corrosion resistance and the wear resistance increase.The studies on tribomodels during the dry friction processes determine the wear intensity for a certain type of tribomodel and for a certain type of material. An Amsler stand was used. The experimental study uses two distinct values of task of loading (Q). The rollers with different diameters were used in order to obtain different sliding degrees (ξ). The Diffractometric aspects have completed this study.A thermo-chemical treatment in plasma with diffusion applied at a temperature under the temperature of the thermo-magnetic treatment leads at high wear resistance and better characteristics of the superficial layers of the steel.Keywords: Steel, thermo-magnetic treatment, wear process
