Powder metallurgy confers the specific properties to the materials by selecting appropriate components with proper compositions. An attempt was made to produce the dense aluminum-based metal matrix composite for the brake lining through powder metallurgy. In this work, two different sintering approaches of microwave sintering and spark plasma sintering were used to obtain the dense material. Based on the properties required for performing the intended functions, the powders of aluminum (80%), boron carbide (8%), silicon dioxide (7%), nickel (3%), and graphite (2%) were used to produce a metal matrix composite (MMC). The particle size, bulk/apparent density, and tap density of each powder were determined using the corresponding tests. The powders were mixed and blended with the help of a high-energy ball mill. The portion of the blended mixture was processed through the microwave sintering, where it was first compacted with the hydraulic press and then sintered at an appropriate sintering cycle. Other samples of the same chemical composition have been prepared using spark plasma sintering, where compaction and sintering occur simultaneously at a particular temperature and pressure. The density and microhardness values from each sample were determined using the Archimedes principle and the Vickers microhardness test, respectively. The SEM analysis was performed to analyze the morphology of the sample material after it has been processed by microwave sintering and spark plasma sintering. From the assessment of the obtained results, it was observed that the spark plasma sintering approach is an appropriate method to produce dense materials.

粉末冶金通过选择具有适当成分的适当成分赋予材料特定的性能。尝试通过粉末冶金生产用于制动衬片的致密铝基金属基复合材料。在这项工作中，使用微波烧结和放电等离子体烧结两种不同的烧结方法来获得致密材料。根据执行预期功能所需的特性，使用铝 (80%)、碳化硼 (8%)、二氧化硅 (7%)、镍 (3%) 和石墨 (2%) 的粉末来生产金属基复合材料 (MMC)。每种粉末的粒度、堆积/表观密度和振实密度使用相应的测试确定。在高能球磨机的帮助下混合和混合粉末。混合混合物的一部分通过微波烧结进行加工，首先用液压机压实，然后以适当的烧结周期进行烧结。使用放电等离子烧结制备了具有相同化学成分的其他样品，其中压实和烧结在特定温度和压力下同时发生。每个样品的密度和显微硬度值分别使用阿基米德原理和维氏显微硬度测试确定。进行SEM分析以分析样品材料经微波烧结和放电等离子烧结处理后的形貌。从对所得结果的评估可以看出，放电等离子体烧结方法是生产致密材料的合适方法。
