To better understand the properties of Mn-23Cu-6Ni alloy, its tribological behavior and wear mechanism were investigated under various conditions, including dry sliding, polyalphaolefin (PAO) lubrication, and PAO lubrication with molybdenum disulfide (MoS₂) additive. The experimental results showed high friction and severe wear when exposed to dry sliding while the running-in process denoted contact under PAO lubrication. MoS₂ nanosheets improved the friction reduction and anti-wear performance of PAO and suppressed the running-in process, rendering the sliding system stable from the beginning. The wear mechanism of the Mn-23Cu-6Ni alloy changed from adhesive wear in dry conditions to abrasive wear when exposed to PAO lubrication with MoS₂ nanosheets.

为了更好地理解Mn-23Cu-6Ni合金的性能，研究了其在各种条件下的摩擦学行为和磨损机理，包括干式滑动，聚α-烯烃（PAO）润滑和含二硫化钼（MoS ₂）添加剂的PAO润滑。实验结果表明，当暴露于干滑下时，高摩擦力和严重磨损，而磨合过程表示在PAO润滑下接触。MoS ₂纳米片改善了PAO的减摩和抗磨性能，并抑制了磨合过程，使滑动系统从一开始就稳定。Mn-23Cu-6Ni合金的磨损机理从干燥条件下的粘合剂磨损变为暴露于MoS ₂纳米片的PAO润滑时的磨料磨损。
