The present investigation pertains to synthesize aluminium bronze silicon carbide composite by powder metallurgy route. Three various weight percentages of silicon carbide (0, 2, 4 & 6) were reinforced with aluminium bronze matrix (Cu-20 %Al-4 %Ni). This compact was heated at two different temperatures such as 650 and 750 °C using tubular furnace. The effect of silicon carbide on density, sinterability, compression test and hardness test was analyzed. The scanning electron microscope and energy dispersive spectroscopy were used to confirm the presence of alloying elements. The results showed that the sinterability and density were reduced with an increase in silicon carbide content. There was significant improvement in densification of composites sintered at 750 °C relative to composites sintered at 650 °C. The maximum percentage of increase in density was 7.34 %, which was noticed for 4 % SiC reinforced aluminium bronze sintered at 750 °C. Aluminium bronze- 4 % SiC composite (750 °C) sintered exhibited maximum hardness of 32HRC. Among the composites sintered at 750 °C, 6 % SiC reinforced possesses lowest sinterability of 0.44.The composite reinforced with 6 %SiC exhibited lowest compressive strength among other composites. The 4 wt% SiC reinforced composites sintered at 750 °C has highest corrosion resistance.There was significant improvement in densification of composites sintered at 750 °C relative to composites sintered at 650 °C.

本研究涉及通过粉末冶金路线合成铝青铜碳化硅复合材料。三种不同重量百分比的碳化硅（0、2、4 和 6）用铝青铜基体（Cu-20%Al-4%Ni）增强。使用管式炉在两种不同的温度（例如 650 和 750 °C）下加热该压块。分析了碳化硅对密度、烧结性、压缩试验和硬度试验的影响。使用扫描电子显微镜和能量色散光谱来确认合金元素的存在。结果表明，随着碳化硅含量的增加，烧结性和密度降低。与在 650 °C 下烧结的复合材料相比，在 750 °C 下烧结的复合材料的致密化有显着改善。密度增加的最大百分比为 7.34%，这是在 750°C 下烧结的 4% 碳化硅增强铝青铜注意到的。铝青铜 - 4 % SiC 复合材料 (750 °C) 烧结后的最大硬度为 32HRC。在 750 °C 烧结的复合材料中，6% SiC 增强的烧结性最低，为 0.44。6% SiC 增强的复合材料在其他复合材料中表现出最低的抗压强度。在 750 °C 烧结的 4 wt% SiC 增强复合材料具有最高的耐腐蚀性。在 750 °C 烧结的复合材料相对于在 650 °C 烧结的复合材料的致密化有显着改善。密度增加的最大百分比为 7.34%，这是在 750°C 下烧结的 4% 碳化硅增强铝青铜注意到的。铝青铜 - 4 % SiC 复合材料 (750 °C) 烧结后的最大硬度为 32HRC。在 750 °C 烧结的复合材料中，6% SiC 增强的烧结性最低，为 0.44。6% SiC 增强的复合材料在其他复合材料中表现出最低的抗压强度。在 750 °C 下烧结的 4 wt% SiC 增强复合材料具有最高的耐腐蚀性。
