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。
In order to investigate the tribological behavior of copper based friction plates for belt conveyor,the Cu-Fe based friction materials were prepared by powder metallurgy technology.The tribological behavior of friction plates under dry braking conditions was studied by ring-block friction and wear tester.The effect of Fe on the friction behavior and wear mechanism of copper-based composite friction plates was studied.The results showed that the copper-graphite composites with Fe added to the copper-graphite composites exhibit better tribological properties under high load,and the graphite-rich mechanical mixing layer（MML） formed on the friction surface was more robust.
