Synergistic lubricating behaviors of graphene and MoS2 dispersed in esterified bio-oil for steel/steel contact

Abstract: Graphene and MoS 2 were dispersed in Esterified Bio-Oil (EBO) and evaluated as lubricants for steel/steel contact. The tribological behaviors of steel/steel pairs were investigated under lubrication of graphene/MoS 2 blends with different mass ratios, loads and rotating speeds.The micro-morphologies of the worn surfaces were observed by optical and Scanning Electron Microscopy (SEM). The components of the additives and chemical valences of the elements on the rubbed surfaces were analyzed using Raman and X-ray… Show more

“…And when the load is 200 N, the lubricity of the material is optimal, which may be due to the interaction between the nanoparticles and the nanosheet and they work as a rolling medium between the contact faces, which confirms the synergistic lubrication between 3D graphene and 2D h‐BN nanoparticles dispersed in the PAO4 oil. These results confirm that the different loads and ratios reported in the literature [ 35–37 ] can significantly change the contact state of the friction pair and affect the lubrication mechanism.…”

“…For the past few years, a lot of additives have been reported to enhance the tribological performance of IL with low friction coefficient and improved anti-wear ability [14][15][16][17]. Two-dimensional materials (TDMs), such as graphene and molybdenum disulfide (MoS 2 ), with outstanding anti-wear and ultralow friction coefficient, have become attractive solid lubricants to be used as additives to enhance a lubricating property of mechanical components [18][19][20][21].…”

“…For instance, surface modification is the most promising method to promote MoS 2 dispersion [15][16][17]. Mixed MoS 2 / graphene dispersions in base oils resist sedimentation for two weeks [18]. MoS 2 with different morphologies and sizes was fabricated and could be dispersed in different oils for a few weeks [19][20][21].…”
