Abstract—

The tribological properties of iron-based powder composite material with the addition of graphite, alumina and zirconia nanoparticles are studied in this paper. Researches have been performed according to “composition–property” experiment design. The momentary friction coefficient in the pair “iron-based powder composite–hardened 45 steel” remains essentially unchanged over time. The minimum friction coefficient has been observed upon the addition of alumina or zirconia and the temperature in the friction area practically does not depend on the type of additive. The complicated influence of additive content on the wear rate of iron-based powder composite material has been determined. The additives synergetic impact makes it possible to significantly decrease the wear rate.

含石墨，氧化铝和氧化锆纳米粒子的铁基粉末复合材料的摩擦学性能

摘要—

研究了添加石墨，氧化铝和氧化锆纳米粒子的铁基粉末复合材料的摩擦学性能。根据“组成－属性”实验设计进行了研究。“铁基粉末复合硬化45钢”对中的瞬时摩擦系数随时间基本保持不变。在添加氧化铝或氧化锆时已经观察到最小的摩擦系数，并且摩擦区域中的温度实际上不取决于添加剂的类型。确定了添加剂含量对铁基粉末复合材料磨损率的复杂影响。添加剂的协同作用可以显着降低磨损率。
