摘要
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.
