ABSTRACT

Duleba A.D., Melnyk O.V. On the theory of the process of boronation of iron-carbon alloys in a magnetic field. Visnyk National Transport University. Series «Technical sciences». Scientific and Technical Collection. - Kyiv: National Transport University, 2020. - Issue 1 (46).

The article offers an analysis of the results of the processes of formation of iron borides from the point of view of quantum theory.

The object of study is the phase composition, physicomechanical and electrophysical properties of boride, borosilicidal and aluminum-boride coatings on iron and steel.

The research method is x-ray and metallographic analysis.

Based on the analysis of the results of the formation of iron borides on boron diffusion from the point of view of quantum theory, it was found that a significant increase in the physicomechanical properties of partially microhardness and wear resistance occurs by establishing stable electronic configurations of chemical compounds. So, when creating FeB compounds, boron atoms (2s22p1) form sp3 configurations due to electrons of iron atoms (3d64s2), which have the donor property to form stable d5 configurations. Experimental studies of the properties of chemical compounds that form during diffusion saturation confirm a correlation with their electronic structure, and iron atoms tend to form a strong covalent bond with boron atoms.

KEY WORDS: BORING, BOROSILICATION, ATOMS, ENERGY LEVELS, QUANTUM NUMBERS, ELECTRON CONFIGURATION.
