- Abstract
The effects of nano-molybdenum disulfide (nano-MoS2) on the tribological behavior of polycrystalline diamond compact (PDC) with a cobalt leaching depth of 422 μm were studied in this research. Ball-on-disk friction tests were conducted to evaluate the impact of nano-MoS2 concentration and bearing capacity on the lubrication effect of drilling fluid and the friction performance of PDC. The results demonstrated that the addition of nano-MoS2 enhanced the lubrication effect of drilling fluid and improved the friction performance of PDC. The study also discussed the lubrication mechanism of drilling fluid and the mechanism by which adding nano-MoS2 enhances tribological properties. These findings contribute to deepen the understanding of the friction and wear mechanism of PDC in lubricating environment, and provide a theoretical reference for the future application of PDC in the petroleum field.
