| 摘 要： | 以氧氯化锆为原料制备纳米ZrO2并对其结构进行了表征;用硅烷偶联剂对其表面进行表面改性处理,使其具有良好的亲油性;用摩擦磨损试验机测定了所制备的纳米ZrO2作为20#机械油添加剂的摩擦磨损性能。结果表明所制备的ZrO2为粒径为10nm左右的球形颗粒,具有无定形晶体结构;纳米ZrO2作为添加剂可以显著提高20#机械油的抗磨减摩性能,当纳米ZrO2的添加量为0.1%(质量分数)时相应的磨斑直径最小、摩擦因数最低、磨损量最少。

| Abstract: | Nano-ZrO2 particles were prepared with zirconium oxychloride octahydrate and modified with silane coupling agent.The structure was characterized by transmission electron microscopy,X-ray powder diffraction and energy dispersive spectroscope.The friction reducing and anti-wear behavior of the ZrO2 used as additive in lubricant oil were analyzed on wear tester.Worn steel surface were analyzed by scanning electron microscopy and energy dispersive spectroscope.Results show that the target nano-ZrO2 particles are spherical-shaped and has a diameter about 10 nm and amorphism structure.As additive,it can increase the antiwear and friction reducing ability of base oil.The 20# base oil doped with 0.1% nano-ZrO2 particles shows the best tribological properties among the tested oil samples. |
