An alloyed steel grade for machine parts construction used in industry have been considered and this material was subjected to a classical improvement treatment or a thermo-magnetic treatment before a plasma nitriding process – the last one being a thermo - chemical treatment. Studying the superficial layer, it was taken in consideration the distribution of the phases in case of the classic treatment procedure versus the case of the non-conventional treatment in magnetic field applied before plasma (ion) nitriding. Plasma nitriding applied after a non-conventional treatment in magnetic field to the steel used in industry, have been studied in this paper. The samples have been tested using an Amsler stand for wear tests (dry friction) and the diffractometric analysis completed this study.This study is a short review of the researches realized in the last few years
