| 摘 要： | 以未处理空心微球材料为原料制备粒度分布均匀集中的空心微球材料,用硅烷偶联剂对其进行表面改性处理,使其具有良好的亲油性。用HQ-1环块试验机在高速低载荷和低速高载荷2种工况下,测定了所制备的空心微球材料作为500SN基础油添加剂的摩擦磨损性能。结果表明:经处理后的空心微球材料可以显著提高500SN基础油的抗磨减摩性能;经处理后的空心微球材料的抗磨减摩性能好于未处理空心微球材料,表明粒径分布对摩擦学性能有显著影响。

| Abstract: | The smaller narrower size distribution and hollow microspheres(HMB) particles were prepared with isolating unsettled hollow microspheres particles and dispersed by silane coupling agent.The friction reducing and antiwear behaviors of the HMB used as additive in lubricant oil were analyzed on HQ-1 wear tester under the conditions of high speed-low load and low speed-high load.Worn surface of steel was analyzed by scanning electron microscopy.Results show that HMB particles can increase the wear resistance and friction-reducing behaviors of 500SN oil.The friction and wear behaviors of HMB are better than that of unsettled hollow microspheres,it is shown that the friction and wear behaviors of hollow microspheres are depended on particle size distribution. |
