Metallic MoS2 enhances the performance of water-based drilling fluids

In this work, the metal phase MoS2 was prepared by a simple one-step hydrothermal method, and it was systematically studied by XRD, Raman, SEM, TEM, and other characterization methods. In addition, the tribological behavior of M-MoS2 in water-based drilling fluids has been extensively studied with a ball-disk tribometer. In addition, the influence of applied load and speed on friction performance is also studied. The experimental results show that the introduction of M-MoS2 significantly reduces the friction and wear of the material. Among them, M-MoS2-5-water-based drilling fluid has the lowest friction coefficient (~0.11).
