将平均直径为7 nm的二氧化硅纳米颗粒添加到水中，在边界润滑条件下，利用球盘摩擦试验机研究了其对Si 3 N4自配滑动偶摩擦的影响。通过向水中添加0.01或0.1wt%的二氧化硅颗粒，在0.21 m/s的滑动速度下，在两种情况下的磨合距离都显著减小，并且在低速条件下（v ≤ 0.12 m/s）产生低且稳定的摩擦（μ 0.05）。在本研究中测试的那些中，用于低且稳定摩擦的二氧化硅的最佳浓度为0.01重量%，这最接近二氧化硅对水的溶解度极限。
Silica nano-particles that have the average diameter of 7 nm were added to water, and their effects on friction were studied for Si3N4 self-mated sliding couples by a ball-on-disk tribotester under boundary lubricated conditions. By adding 0.01 or 0.1 wt % of silica particles to water, the running-in distance was reduced significantly in both cases at the sliding velocity of 0.21 m/s and resulted in low and stable friction (μ 0.05) under low velocity conditions (v ≤ 0.12 m/s). The optimum concentration of the silica for the low and stable friction was 0.01 wt % among those tested in this study, which is the closest to the solubility limit of silica to water.
