采用往复滑动球-板摩擦磨损试验机研究了添加和不添加纳米颗粒的基础润滑剂对镁合金/钢接触摩擦学性能的影响。采用三组接触条件分别评价了浓度效应、承载能力和润滑膜稳定性。结果表明，纳米粒子的加入改善了基础润滑油的摩擦学性能。与SiO2纳米润滑剂相比，MoS 2纳米润滑剂在承载能力和润滑膜稳定性方面的积极效果更明显。纳米润滑剂改善摩擦学行为的机制进行了讨论。(C)2015爱思唯尔有限公司版权所有。
The effects of the base lubricant with and without nanoparticles on the tribological behavior of magnesium alloy/steel contacts were investigated using a reciprocating sliding ball-on-flat tribometer. Three sets of contact conditions were used to evaluate the effect of concentration, the capacity of carrying load and the stability of the lubrication film, respectively. The results showed that the tribological properties of the base lubricant have been improved by adding the nanoparticles. As compared with the SiO2 nanolubricants, the positive effect of the MoS2 nanolubricants is more pronounced in terms of the load carrying capacity and the lubrication film stability. Mechanisms by which the nanolubricants improve tribological behaviors are discussed. (C) 2015 Elsevier Ltd. All rights reserved.
