摘　　要：用硅烷偶联剂WD-10对不同粒径的高铝空心微球表面改性。以改性高铝空心微球(HAHM)作为润滑添加剂,在MMW-1P型摩擦磨损试验机上测定添加不同粒径HAHM的500SN基础油的摩擦系数,考察HAHM添加量、粒径和载荷对润滑油摩擦系数的影响。结果表明,HAHM在500SN基础油中能较稳定分散;HAHM的添加量和平均粒径都对其摩擦学性能有影响,其中添加0.2%(质量分数)的HAHM-b的500SN基础油的摩擦系数最小,减摩性能最好。Different size high-aluminous hollow microspheres were surface-modified by silane coupling agent WD-10.The surface-modified high-aluminous hollow microspheres（HAHM） were used as the lubricating additive of 500SN base oil.The frictional coefficients of 500SN with different particle sizes and different amounts of HAHM added were analyzed on MMW-1P wear tester.Results showed that HAHM could be dispersed steadily in lubricant oil.The particle size and addition amount of HAHM could influence the frictional coefficient of lubricant oil.In three tested HAHM samples,the HAHM-b with the addition amount of 0.2% made the frictional coefficient of lubricant oil being smallest.
