摘要:

采用磁控溅射技术制备了MoS2/Zn润滑薄膜,研究了原子氧MoS2薄膜摩擦磨损性能的影响规律。结果显示,Zn的掺入促使MoS2沿平行于(002)晶面的方向择优生长,薄膜结构致密有序,可有效抑制原子氧向薄膜内部侵蚀。转速2 r/min、MoS2靶电流1.6 A、Zn靶电流0.3 A的MoS2/Zn多层薄膜的摩擦因数为0.02、磨损率为1.9×10-7 mm3/(N·m)。原子氧环境中,MoS2/Zn多层薄膜展示出更好的摩擦学性能,在6.12×1020 atoms/cm2的辐照剂量下,MoS2/Zn多层薄膜的平均摩擦因数降至0.01,其性能提升主要源于辐照产生的MeO x 和MoS2的协同作用。

Abstract:

MoS2/Zn lubricating films were prepared by magnetron sputtering, and the influences of atomic oxygen on tribological properties of the films were investigated. Results show that Zn incorporation promotes the preferential growth of MoS2 along the direction parallel to the (002) crystal plane, resulting in a dense and ordered film structure that effectively suppresse atomic oxygen erosion into the film. The friction coefficient of the MoS2/Zn multilayer film is as 0.02 and the wear rate is as 1.9×10⁻⁷ mm³/(N·m) under atomic oxygen conditions (rotation speed is as 2 r/min, MoS2 target current is as 1.6 A, and Zn target current is as 0.3 A). The MoS2/Zn multilayer films exhibite better tribological properties in atomic oxygen environment. Under an irradiation dose of 6.12×1020 atoms/cm², the average friction coefficient of the MoS2/Zn multilayer film decreases to 0.01. This performance improvement mainly stemmed from the synergistic lubrication effects between MeO x formed after irradiation and the residual MoS2.
