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.

Abstract:
This paper briefly describes how to estimate numerically the quantitative uncertainty of potentiodynamic polarization curves obtained from a charge transfer controlled reaction in the case of working electrodes made from C45 steel with specific coatings (WC-Co, WC-Co-Al2O3 and a reference without coatings). The processed dataset was created during a real physicochemical experiment, but potentiostat/galvanostat transformed the dataset of measurements into parameters of Tafel’s lines without uncertainty estimation.

Abstract:
This article presents the results of studying the structural-phase state changes of Ti-Al coatings on the surface of titanium synthesized by mechanical alloying. The study of the substrate-coating boundary showed the practical absence of traces of diffusion of the coatings in the titanium substrate after the mechanical alloying process. [..]

Abstract:
Research conducted in many scientific centers on the operational properties of machine parts has shown that one of the critical components affecting the fatigue strength of parts is the condition of the surface integrity of their ingredients. In the case of elements produced by electrical discharge machining, the processes occurring during removal of the material: thermal and chemical, constitute the surface layer with different properties to the bulk material.
