| 摘 要： | 采用水热法合成了在液体石蜡中具有良好亲和性和稳定性的Fe3O4/油酸(OA)纳米粒子。四球测试实验结果表明:Fe3O4/OA纳米粒子作为液体石蜡添加剂具有良好的摩擦学性能。当Fe3O4/OA的添加量为0.25%时,可使摩擦因数和磨斑直径分别减小68.2%和16.9%。试球磨斑表面的SEM分析表明:Fe3O4/OA纳米粒子在磨损表面微观缺陷区域有良好的表面修饰作用,避免了摩擦副的直接接触,减少了摩擦界面的黏着磨损,进而有效地提高了液体石蜡的摩擦学性能。

| Abstract: | Fe3O4/oleic acid(OA) nanocomplexes with excellent compatibility and stability in liquid paraffin(LP) were prepared through hydrothermal method.The four-ball test results show that Fe3O4/OA nanocomplexes as additives in LP exhibit good tribological property.As the addition of Fe3O4/OA is 0.25%,the friction coefficient and wear scar diameter are reduced 68.2% and 16.9% respectively.SEM morphologies of the worn steel surface indicate that Fe3O4/OA nanocomplexes show perfect repairing ability in the micro defec... |
