摘要
在水-醇混合介质中采用阳离子共沉淀表面修饰法,制备了硬脂酸修饰的CeF3纳米微粒,利用透射电子显微镜(TEM)对其形貌进行了表征.在四球摩擦磨损试验机上考察了CeF3纳米微粒摩擦学特性.结果表明,表面修饰CeF3纳米微粒在有机溶剂中具有良好的分散性和稳定性,作为润滑油添加剂,显示出良好的减摩、抗磨和承载性能.
Stearic acid modified CeF3 nanoparticles were synthesized by precipitation method.The dispersibility and stability of nanoparticles additives in solvent were studied.The morphology of nanoparticles were investigated by transmission electron microscopy（TEM）.The tribological properties of the modified CeF3 nanoparticles as additives in liquid paraffin were examined with four-ball machine.The results showed that the modified CeF3 nanoparticles exhibit good dispersity and stability in the organic solvent,and showed very good antiwear properties and load-carrying capacity.
