【摘要】:为探究带式运输机铜基摩擦片的摩擦学行为,采用粉末冶金工艺制备Cu-Fe基摩擦材料。在干式制动条件下用环-块摩擦磨损试验机研究摩擦片的摩擦学行为。探索铁元素对铜基复合材料摩擦片摩擦行为和磨损机理的作用。结果表明,与铜-石墨复合材料相比,添加了铁元素的铜-石墨复合材料在高载荷下表现出更好的摩擦学性能,其在摩擦表面上形成的富含石墨的机械混合层(MML)更加稳定。
[Abstract]:In order to investigate the tribological behavior of copper-based friction sheet of belt conveyor, Cu-Fe-based friction material was prepared by powder metallurgy process. The tribological behavior of friction plate was studied by ring-block friction and wear tester under dry braking condition. The effect of iron on the friction behavior and wear mechanism of Cu-based composites was investigated. The results show that compared with Cu-graphite composites, Fe-Cu-graphite composites exhibit better tribological properties under high load, and the graphite-rich mechanical mixing layer (MML) formed on the friction surface is more stable.
