Abstract The tribological performance of biocarbon-based magnesium silicate hydroxide nanocomposite was examined as a lubricant additive by using a four-ball friction and wear tester. The effect of different concentrations of additives and dispersants was evaluated. The results show the nanocomposite exhibits excellent anti-wear performance and the optimal value is proposed when the content of additive and dispersant is 0.7 wt% and 3 wt% respectively. Through analyzing the friction surfaces by scanning electron microscope and Raman, we proposed the additives acted by a combination of “bearing,” “third body,” and sliding effect to achieve outstanding tribological properties.

Abstract Biocarbon-based magnesium silicate hydroxide(M@C-ON) was synthesized by hydrothermal method with synthesized magnesium silicate hydroxide (MSH) as the template, glucose as carbon source, and oleylamine (ON) as the modified agent. The dispersion stability of M@C-ON as lubricant additive in PAO10 with ON as dispersant was measured by accelerated centrifugal and static sedimentation test. The results showed that M@C-ON, with the help of ON, can be stably dispersed in lubricating oil for at least 15 days. The stable dispersion was attributed to a combination of electrostatic attraction and steric hindrance. Besides, the tribological properties of M@C-ON as lubricant additive was tested under different concentration of additive and dispersant. A continuous carbon layer formed on the contact area and the repairing effect of inner MSH of M@C-ON were considered as the factors to play an anti-wear effect.
