“…Meanwhile, by the method of high-energy mechanical ball-milling, only micro-sized natural serpentine particles can be obtained, which is not suitable for their applications as lubricant additives. Inspired by the above research studies, we have synthesized MSH nanoparticles and confirmed its outstanding tribological properties in base oil [16][17][18].…”

This paper reports the synthesis of magnesium silicate hydroxide (MSH) nanoparticles and their synergistic tribological properties combined with amphiphilic molecules (AMs) as additives in base oil. This combination reduces wear losses substantially due to the formation of a double well-arranged molecular layer or tribofilm on the rubbing surfaces under certain test conditions. From the results of nonequilibrium molecular dynamics (NEMD) simulations, lamellate MSH nanoparticles provide a medium for the adsorption of AMs thus further decreasing the contact of rough peaks. In addition, with the increase of load, a tribofilm containing element Mg, Si, O forms on the worn surfaces and greatly improves the anti-wear property of base oil.

“…Layered nanoparticles, such as graphite, MoS 2 , and boron nitride, maintain the characteristics of larger surface area and higher diffusivity compared with ordinary morphology particles, making flake materials as new type of lubricant additives. Further, layered silicate was considered as one of the best candidate materials because of their low cost, nontoxic, and stability properties. Gao et al synthesised magnesium silicate hydroxide (MSH) by hydrothermal method at 200°C for 12 hours with magnesium oxide and silica as raw materials.…”

Talc/carbon spheres (TC) composite was successfully fabricated through a simple and eco-friendly hydrothermal method. The tribology properties of the base oil were significantly improved after adding TC composites, which had been studied by a ball on disc (BOD) tribometer. The friction coefficient of oil containing 0.5-wt% TC composite (0.5 TC-Oil) was only 0.08, with a decrease of 35.3% compared with the base oil at 5 N. Moreover, severe abrasive wear between friction pairs changed into slight plastic deformation lubricated with 0.5 TC-Oil, as confirmed by scanning electron microscope (SEM). These results reflected notable synergy between self-repair performance effect of talc and ball-bearing effect of carbon spheres. The study displayed the potential lubricating performance of the TC composite in current generation oil lubricants.

“…Magnesium silicate hydroxide (MSH) is the main component of serpentine minerals, which display excellent friction reduction, compression resistance and self-repair. It is easy to form an oxidation protective layer with good wear resistance and high hardness on the surface of friction couple, so it can be used as an oil additive [ 24 , 25 ]. In this work, MSH nanoparticles were synthesized by a one-step hydrothermal method, using nano-SiO 2 and MgO as raw materials.…”

In this study, crumpled graphene balls (CGB), a kind of nano-material, was used as an additive to improve the tribological properties of base oil. Nano-magnesium silicate hydroxide (MSH)/CGB composites were prepared by ultrasound-assisted liquid-phase exfoliation. The loading of MSH significantly increased the number of pleats and reduced the lamellar thickness of CGB. Then, in order to improve the compatibility with the base oil, the MSH/CGB composites were decorated with oleic acid and stearic acid to get modified lipophilic composites (ML-MSH/CGB). The ML-MSH/CGB were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). In addition, the tribological properties of the ML-MSH/CGB in base oils were investigated using a ball-on-disc setup tribometer. It indicated that the fantastic tribological behavior of the ML-MSH/CGB in base oil may contribute to a smaller and extremely wrinkled laminated structure. Furthermore, the base oil with 0.005 wt% ML-MSH/CGB composites exhibited the best anti-friction effect, and its average friction coefficient, wearing capacity and wear scar diameter were reduced by 25.4%, 22.1% and 16.7%, respectively. The introduction of ML-MSH/CGB composed materials is an excellent strategy to optimize the friction performance of lubricating oil.
