Abstract

In the last 20 years, the technical progress made it possible the use of very hard materials in several fields like manufacturing parts for the car industry, the pieces for railroad, for nuclear power, in aeronautics and in the mechanical industries.In this paper, it was studied the evolution of the superficial layer at the steel subjected to a non-conventional treatment, during the wear tests. It is a rundown of the results obtained. The material was subjected to the thermo-chemical treatment (plasma nitro-carburizing treatment, or ion nitriding, or laser nitriding treatment) applied after thermo-magnetic treatment regimes.The structural aspects of the superficial layers of the steel are studied before the wear process. The wear process was studied using an Amsler type machine, taking two sliding degrees at a constant contact pressures and the testing was done in time. The tests were done to detect the sustainability to the material, the evolution of the superficial layer characteristics through different of wear tests and to establish the influence of these thermo-magnetic treatments regimes.
