摘要
半金属制动片是性能驱动型汽车工业的理想选择，因为它能在更大的温度范围内提高制动性能。本研究通过粉末冶金加工技术，采用铜（Cu）、铁（Fe）、闪锌矿、氧化铝（Al2O3）、硫酸钡（BaSO4）、酚醛树脂、低密度聚乙烯（LDPE）和石墨两种不同重量比的粉末成分，制备了一种半金属刹车片，用于汽车应用。从微观结构上看，硬质颗粒均匀地分散在整个基体中，显示出良好的成分分布。BP-20Cu-20Fe 试样的硬度值高达 171Hv。在 70 N 的较高负载下，BP-20Cu-20Fe 试样表现出优异的耐磨性，磨损率低至 1.072×10-6 g/Nm。另一方面，当载荷从 30 N 增加到 70 N 时，试样 BP-20Cu-20Fe 的摩擦系数显著增加了 35%。
Development and Tribological Characterization of Semi-Metallic Brake pads for Automotive Applications
Semi-metallic brake pads are quite a good choice for performance-driven automotive industries, because of improved braking performance in a more comprehensive range of temperatures. In this study, a semi-metallic brake pad is fabricated through a powder metallurgy processing technique with two compositions of powders with a different weight ratio of Copper (Cu), Iron (Fe), flash, Aluminum oxide (Al2O3), Barium sulfate (BaSO4), Phenolic resin, Low-Density Polyethylene (LDPE), Graphite for automotive application. A well-distributed composition was indicated by the microstructure, which exhibited a uniform dispersion of hard particles throughout the matrix. BP-20Cu-20Fe specimen exhibited a high hardness value of 171Hv. Under higher loads of 70 N, the specimen BP-20Cu-20Fe showed excellent wear resistance, with a low wear rate of 1.072×10-6 g/Nm. On the other hand, specimen BP-20Cu-20Fe showed a notable 35% increase in friction coefficient when the load was increased from 30 N to 70 N.The surface morphology, elemental distribution, and worn surface features and characteristics are examined using advanced instrumental techniques.
