Biocarbon-based magnesium silicate hydroxide (M@C-ON) was synthesised by hydrothermal method with synthesised magnesium silicate hydroxide (MSH) as the template, glucose as carbon source and oleylamine (ON) as the modified agent. The outstanding dispersion stability of M@C-ON as lubricant additives in PAO10 with ON as dispersant was proved by accelerated centrifugation and static sedimentation tests. The tribological properties of M@C-ON as lubricant additive were tested under different concentrations and working conditions, and it was found that oil samples containing M@C-ON as additive showed enhanced tribological properties than that containing MSH under 600 N, 600 RPM. At the same time, the anti-wear performance was thought to be affected by the external energy acted on nano-additives. When M@C-ON as additive fully functioned, 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 role.

油胺改性的生物碳基氢氧化硅酸镁具有优异的分散稳定性和增强的摩擦学性能

以合成的氢氧化硅酸镁（MSH）为模板，葡萄糖为碳源，油胺（ON）为改性剂，采用水热法合成了生物炭基氢氧化硅酸镁（M@C-ON）。通过加速离心和静态沉降试验证明了 M@C-ON 作为润滑剂添加剂在以 ON 作为分散剂的 PAO10 中具有出色的分散稳定性。对作为润滑油添加剂的 M@C-ON 在不同浓度和工况下的摩擦学性能进行了测试，发现在 600 N、600 RPM 下，含有 M@C-ON 作为添加剂的油样比含有 MSH 的油样表现出更强的摩擦学性能。 . 同时，抗磨性能被认为受作用于纳米添加剂的外部能量的影响。当 M@C-ON 作为添加剂充分发挥作用时，
