Abstract
We study the dynamics of changes in the microstructure and microtopography of gray and high-strength cast irons, containing 0.05 to 11 vol. % of phosphide eutectic, under conditions of dry and boundary friction (45 steel serves as an antibody). We have established that the physicomechanical properties of phosphorous cast irons are greatly affected by the distribution and morphology of phosphide eutectic. As a result of friction, phosphide eutectic is localized in thin (to 5 µm) subsurface layers of the metal and redistributed, and its area on the surface increases by 20 to 30%. We have also substantiated the mechanism of influence of phosphide eutectic on the wear resistance of phosphorous cast irons. Temperature flashes on the inclusions of phosphide eutectic lead to their plasticization, increase their area on the friction surface, decrease the contact pressures, reduce the mean integral temperature, and enhance the wear resistance of cast irons.
