A thermo-magnetic treatment applied before plasma nitriding modifies the characteristics of the mechanical resistance of the steel, the hardness and the resistance of the material during corrosion process. A non-conventional treatment applied to steel for industrial gearings have been studied in this paper. It have been demonstrated that the energy of the magnetic field conduct to the mechanical oscillations of micro-areas in material and intervenes in the balance of the global power of the phase transformations in solid state changing the thermodynamics, kinetics and the mechanisms of the processes, the microstructures and properties of the steel. The wear tests (dry friction) have been realized using an Amsler stand. The plasma nitriding plant used was the INI 150 which was made by the Institute of Radiation Physics and Technology in collaboration with the "Electrotechnics" Enterprise and the Nuclear Apparatus from Romania, used for industrial nitriding of small pieces. INI 150 was based on the physical phenomenon of a double cathode at plasma (ion) nitriding. This work is a review of my researches from the last years.
