The possibility of increasing the durability of steel pins working against bronze bushings through plasma–electrolytic nitrocarburizing of the surface of medium carbon steel is shown. The phase composition, microhardness, morphology, and surface roughness were studied. Tribological tests were carried out under dry friction conditions according to the shaft-pad scheme. It has been established that plasma–electrolytic nitrocarburizing of the surface of medium carbon steel at a temperature of 700 °C for 5 min leads to a decrease in the friction coefficient by 2.3 times, the weight wear of steel by 24.9 times, and the wear of the bronze counterbody by 5.9 times. At the same time, the contact stiffness increases by 2.6 times. Type of wear: wear with dry friction and plastic contact. The changes in tribological characteristics are associated with the high hardness of the hardened steel surface combined with the effect of dispersed nitrides and iron carbonitrides.

The possibility of increasing the resource of steel fingers working in tandem with bronze bushings by plasma-electrolytic nitrocarburizing of the surface of medium carbon steel is shown. The phase composition, microhardness, morphology and surface roughness were studied. Tribological tests were carried out under dry friction conditions according to the shaft-pad scheme. It has been established that plasma-electrolytic nitrocarburizing of the surface of medium carbon steel at a temperature of 700 °C for 5 minutes leads to a decrease in a friction coefficient by 2.3 times, weight wear of steel by 24.9 times, and bronze counterbody by 5.9 times. At the same time, the contact stiffness increases 2.6 times. The type of wear is fatigue with dry friction and plastic contact. Changes in tribological characteristics are associated with the high hardness of the hardened steel surface together with the influence of dispersed nitrides and iron carbonitrides distributed in it.

This paper investigates the relationship between the predicted interface flash temperature and the experimentally measured temperature when two solids are in contact sliding. To reveal this, both pin-on-disc experiments and finite element simulations were carried out systematically. The infrared technique was used to experimentally measure the interface temperature. Bulk metallic glass was especially selected as the pin material because this material can have microstructural changes to record its temperature history experienced. Transmission electron microscopic analysis showed that nanocrystallisation occurred during the contact sliding, showing that the temperature at the real contact area must have exceeded glass transition temperature, Tg of the bulk metallic glass and reached its onset temperature of crystallisation Tx. However, the temperature measured was much less than the glass transition temperature Tg. On the other hand, the finite element analysis showed that the temperature at the pin surface was beyond Tg when the flash temperature reached Tx. The study thus concluded that there exists a thermal resistance due to the complex surface morphology of rough surfaces, which alters the thermal conductance in the neighbourhood of the contact interface.
