本文研究液晶润滑添加剂的抗磨性能。将1％正辛基苯甲酸液晶材料加入至HU-20汽轮机油中,在Falex试验机上试验结果表明具有降低磨损量和缩短磨合时间的作用,与不加添加剂时相比较,线磨损量降低44％,摩擦系数降低31～47％,磨合时间缩短一倍。在四球试验机上试验,最大无卡咬负荷P_B值增加21％。液晶添加剂对改善润滑油的抗磨性能作用明显。 This article studies the anti-wear properties of liquid-crystal lubricant additives. 1% n-octylbenzoate liquid crystal material was added to HU-20 turbine oil test results on the Falex test machine shows the effect of reducing the amount of wear and shorten the run-in time, compared with no additives, reduce the amount of wire wear 44 %, The friction coefficient is reduced by 31 ~ 47%, and the run-in time is doubled. In the four-ball test machine test, the maximum card-free bite load P_B value increased by 21%. Liquid crystal additives to improve the anti-wear properties of lubricants obvious role.
