Copper-based sintered friction materials are most suitable for heavy-duty off-road vehicles, trains, aircraft, and military applications. This present study aims to investigate the tribological performance, dominating wear mechanism of an existing copper-tin sintered friction material that is being used in armoured fighting vehicle. The brake pad was tested as per IS 2742 using the chase test machine. Especially fade cycle was carried out till 441℃ to analyze the frictional response of the material. Physical, mechanical, and tribological properties were evaluated as per industrial standards. Morphological analysis was carried out using field emission scanning electron microscopy, and wear debris analysis was carried out using scanning electron microscopy–energy dispersive X-ray analysis and X-ray diffraction analysis. The dominating wear mechanisms were found to be delamination and abrasive wear. The investigated results showed a less wear rate of 0.05 cm3/MJ. However, results seem to be better for high-energy applications by exhibiting excellent mechanical properties.

越野车Cu-Sn烧结刹车片摩擦学性能案例研究

铜基烧结摩擦材料最适合重型越野车辆、火车、飞机和军事应用。本研究旨在研究用于装甲战车的现有铜锡烧结摩擦材料的摩擦学性能和主要磨损机制。刹车片根据 IS 2742 使用追逐测试机进行测试。特别是在441℃进行褪色循环以分析材料的摩擦响应。根据工业标准评估物理、机械和摩擦学性能。使用场发射扫描电子显微镜进行形态分析，使用扫描电子显微镜-能量色散X射线分析和X射线衍射分析进行磨屑分析。发现主要的磨损机制是分层和磨料磨损。研究结果表明磨损率较低，为 0.05 cm3/MJ。然而，通过表现出优异的机械性能，结果似乎更适合高能应用。
