摘　　要：采用水热法合成MoS_(2)/Ag_(2)S复合纳米材料,并采用XRD、SEM及TEM对材料的组分与结构进行表征,考察其作为润滑油添加剂的摩擦学性能。结果表明:添加MoS_(2)/Ag_(2)S复合纳米材料均具有优异的摩擦学性能,特别是添加3%MoS_(2)/Ag_(2)S的样品,其摩擦系数最低可至0.08。磨痕测试试验进一步证明,MoS_(2)/Ag_(2)S纳米颗粒进入润滑体系,能转移至摩擦副起到自修复的作用,抗磨减磨效果明显。Ag_(2)S/MoS_(2)heterojunctions composed of Ag_(2)S nanoparticles decorated on flower-like MoS_(2)nanosheets were synthesized via a one-step hydrothermal approach.The samples were systematically characterized by XRD,SEM and TEM analysis.Tribological experiments were conducted using a ball-plate wear instrument to compare liquid paraffin containing various Ag_(2)S/MoS_(2)samples.Tribological variables,including applied load and rotational speed,indicated that Ag_(2)S/MoS_(2)heterojunctions provided excellent antifriction and wear resistance compared to other nano-additives.Under optimal conditions,3%Ag_(2)S/MoS_(2)sample exhibited the lowest friction coefficient,reaching 0.08.Wear tests further confirmed that Ag_(2)S/MoS_(2)nanoparticles entering the lubrication system could transfer to the friction pair and act as selfrepairing agents,resulting in significant anti-wear and friction-reduction effects.
