摘　　要：采用焦炭、MoS2和石墨作为减摩剂制备树脂基摩擦材料,通过正交试验和极差分析法,研究3种减摩剂对材料摩擦磨损性能的影响及其协同作用规律。结果表明:在实验用量范围内,焦炭能够提高材料整体摩擦因数,降低材料总磨损率;MoS2能够降低材料中低温摩擦因数,提高高温摩擦因数,但材料的总磨损上升;石墨能够降低材料整体摩擦因数,对材料总磨损率影响不明显。以材料摩擦因数标准差为实验指标时,发现3种减摩剂之间存在强烈的协同作用,且作用程度随着温度的升高而加强,其中焦炭和石墨的协同作用最为强烈;以材料总磨损率为实验指标时,发现3种减摩剂之间的协同作用在中低温下变化趋势一致,在高温下变化趋势不同。Resin-based friction materials were prepared with coke,MoS2 and graphite as friction reducing agents.The effects of three friction reducing agents on friction and wear properties of materials and their synergistic effects were studied by orthogonal experiment and range analysis.The experimental results show that,in the range of experimental dosage,coke can improve the overall friction coefficient and reduce the total wear rate of the materials;MoS2 can reduce the friction coefficient at low temperature,and increase the friction coefficient at high temperature,and increase the total wear rate of the materials;Graphite can reduce the overall friction coefficient of the materials,and has no obvious effect on the total wear rate of the materials.When taking the standard deviation of material friction coefficient as the experimental index,it is found that there is a strong synergistic effect among the three friction reducing agents,and the degree of synergistic effect is enhanced with the increase of temperature,among which the synergistic effect between coke and graphite is the strongest.When taking the total wear rate of materials as the experimental index,it is found that the synergistic effect among the three friction reducing agents has the same trend at low temperature,but different at high temperature.
