摘要

PA66 具有优异的耐高温、高强度、自润滑和耐摩擦性能,是塑料齿轮的常用材料。本研究使用针盘试验台研究了不同湿度水平对 PA66 材料在自配接触中的摩擦学特性的影响。结果表明,湿度处理后 PA66-PA66 滑动组合的摩擦系数和磨损率急剧增加,主要原因是吸水导致表面塑化,以及内聚强度和玻璃化转变温度降低。此外,吸湿后 PA66 材料的极限 PV 值明显降低,当实际 PV 值超过这个降低的材料极限值时,摩擦和磨损程度会急剧增加。PA66-PA66 滑动组合的磨损机理主要是未经湿度处理的粘着磨损。经过湿度处理(50%、70%、90%,浸入水中)后,磨损机理是粘着磨损与磨料磨损相结合,在湿度为 50%时,磨料磨损最为显著。磨料磨损随着湿度的增加而减小,而粘着磨损则增加。

Effect of Humidity on the Tribological Properties of PA66 Gear Materials

PA66 is a commonly used material for plastic gears due to its excellent high-temperature resistance, high strength, self-lubrication, and friction resistance. In this study, the effect of different humidity levels on the tribological properties of PA66 materials in self-mated contacts are investigated using a pin-on-disk test rig. The results show that the friction coefficient and wear rate of the PA66-PA66 sliding combination increase drastically after humidity treatment mainly due to the surface plasticization caused by water absorption and the decrease of cohesive strength and glass transition temperature. Moreover, the limiting PV value of PA66 materials decreased significantly after moisture absorption, and when the actual PV value exceeds this reduced material limit, the degree of friction and wear increases drastically. The wear mechanism of the PA66-PA66 sliding combination is mainly adhesive wear without humidity treatment. The wear mechanism is adhesive wear combined with abrasive wear after humidity treatment (50%, 70%, 90%, immersion in water) and abrasive wear is most significant at 50% humidity. Abrasive wear decreases with the increase of the moisture content, while adhesive wear increases.
