Microwave-synthesized SiO₂-reinforced B-N-co-doped reduced graphene oxide (SiO₂-B-N-GO) nanocomposites were characterized by X-ray photon spectroscopy (XPS), X-ray diffraction (XRD), infrared (IR) spectroscopy, and transmission electron microscopy/energy dispersive X-ray (TEM/EDX) analysis. The tribological properties of the SiO₂-B-N-GO prepared as anti-wear additives for enhanced lubrication were studied using a four-ball tester. The experiment results indicated that SiO₂-B-N-GO exhibits excellent load-carrying, anti-wear, and anti-friction properties in a base oil, especially at the optimal concentration of additives at 0.15 wt%. The wear scar diameter decreased from 0.70 to 0.37 mm and the coefficient of friction was reduced from 0.092 to 0.070, which reductions are attributed to the formation of B-N and graphene layer tribofilms of several tens of nanometers in thickness that prevented direct contact between metals.

微波合成的SiO ₂增强的BN共掺杂的还原氧化石墨烯（SiO ₂ -BN-GO）纳米复合材料的特征在于X射线光子光谱（XPS），X射线衍射（XRD），红外（IR）光谱，以及透射电子显微镜/能量色散X射线（TEM / EDX）分析。使用四球测试仪研究了用作增强润滑的抗磨添加剂SiO ₂ -BN-GO的摩擦学性能。实验结果表明SiO ₂-BN-GO在基础油中表现出优异的负载，抗磨和抗磨性能，尤其是在添加剂的最佳浓度为0.15 wt％时。磨痕直径从0.70降低到0.37 mm，摩擦系数从0.092降低到0.070，其减少归因于形成BN和数十纳米厚的石墨烯层摩擦膜，从而阻止了金属之间的直接接触。
