Abstract
An experimental study was performed to measure increased durability using the sample alloyed steel and carbon steel frictional pair. The study measured the effects of magnetic treatment of alloyed steel on diffusion transfer of alloying elements during friction into mating carbon steel. Measurements of the microhardness of the surface layer of carbon steel after friction without the use of magnetic treatment revealed the formation of secondary structures with high hardness. The decisive role is played by the mechanisms of chemical nature, the manifestation of which is due to the processes of enhanced mechanical activation and intensive deactivation of the adjacent layers of crystal lattices. The effect of preliminary magnetic treatment on a sharp decrease in the efficiency of formation of solid structures during friction has been established. The study of the elemental content of the surface layer of carbon steel after friction by spectral analysis established the diffusion transfer of carbide-forming elements and its significant deceleration in the processing of alloyed steel with a magnetic field. Based on a comparison of experimental results, it was shown that solid secondary structures can be carbide phases and intermetallic compounds with an increased share of covalent bonding, which is inherent in these chemical compounds precisely.
