| Abstract: |
In low earth orbit, the friction properties of molybdenum disulphide (MoS2) are influenced by atomic oxygen (AO). In this work, an AO impacts model and a sliding contact model are developed, and the friction properties of MoS2 films impacted by the AOs are conducted by using ReaxFF molecular dynamics simulation. The oxidation products formed under the impact of the AOs are analysed, and the migration of AOs within the MoS2 film is discussed. The sliding contact processes make the coefficients of friction (COFs) increase initially and then follow stable values. A worn-out phenomenon is discovered at the final stage of the sliding contact process. As the sliding velocity increases, the COFs and surface temperatures of the MoS2 films fluctuate greatly.
