Tribological behaviours of plasma electrolytic borocarburized Q235 low-carbon steel at ambient and high temperature
Plasma electrolytic boronizing is a novel technique to fabricate rapidly boride layer on steel in order to improve the wear resistance. In this study, a boride layer on Q235 low-carbon steel was prepared by plasma electrolytic borocarburizing process (PEB/C) in the borax electrolyte with carbon organic additive. The microstructure and phase constituent of the PEB/C steel were analyzed by SEM and XRD. Microhardness profile of the PEB/C steel was determined using a microhardness tester, and its tribological properties under dry sliding were evaluated using a pin-disc wear tester at ambient temperature and high-temperature environments up to 500℃. Wear volume and wear rate before and after PEB/C treatment were measured and calculated. The wear mechanism was also discussed. It was found that the (PEB/C) treatment could significantly decrease the friction coefficient and improve wear resistance of the low carbon steel. Meanwhile, plasma electrolytic borocarburized low-carbon steel also maintains higher wear resistance at high temperature environment.
