利用一步水热法制备了氧并入二硫化钼(O-MoS_2)纳米花,该纳米花由大量O-MoS_2纳米片组装而成.由于氧元素的并入,使得MoS_2中(002)晶面间距从6.15?增大至10.5?.利用SRV-I微振动摩擦磨损试验机考察了O-MoS_2纳米花作为添加剂在PAO-8基础油中的摩擦学性能,结果表明:O-MoS_2纳米花的加入可显著改善PAO-8油的减摩抗磨性能,这主要是由于膨胀的层间距有利于MoS_2沿(002)晶面发生滑移.其中,当O-MoS_2纳米花的添加含量为0.1 mg/m L时,润滑油的抗磨损性能最佳.
The O-MoS_2 nano-flower was prepared by a one-step hydrothermal method. The nano-flower was assembled by a large number of O-MoS_2 nanosheets. Due to the incorporation of oxygen, the (002) And the distance between them increased from 6.15 to 10.5. The tribological properties of O-MoS_2 nano-flower as additive in PAO-8 base oil were investigated by using SRV-I micro vibration friction and wear tester. The results showed that the O-MoS_2 nano-flower The friction and wear resistance of PAO-8 oil can be significantly improved by the addition of intumescent layer, which is mainly attributed to the expansion of interlayer spacing and the slip of MoS_2 along (002) plane, in which, when the content of O-MoS_2 nanoflower is 0.1 mg / m L, the lubricant has the best wear resistance.
