| Popis: | The synergistic effects between sulfurized-nanocrystallized 316L stainless steel and molybdenum dithiocarbamates (MoDTC) additive under boundary lubrication were investigated in this paper. The tribological behaviors of the treated steel were investigated on a ball-on-disc SRV tribometer. The chemical analysis of tribofilms was performed by X-ray photoelectron spectroscopy (XPS). The results showed that the sulfurized-nanocrystallized sample exhibited the lowest coefficient of friction (0.060) and the lowest wear rate under MoDTC lubrication. The sulfurized ultrasonic cold forging technology (UCFT) composite treatment provided a strong support to the soft FeS layer and prolonged its service time. The MoS2 decomposed by MoDTC can achieve the lowest coefficient of friction. |
