In this work Copper based composites were synthesized from Cu and SiC powders using Powder Metallurgy (PM) technique. The composition of the composites are Cu, Cu-5 wt% SiC, Cu-10 wt% SiC and Cu-15 wt% SiC were made using 400 kN hydraulic press and sintered at 900 °C using muffle furnace for 4 h. Scanning Electron Microscope (SEM) analysis was done on ball milled powders and sintered samples showed the uniform dispersal of SiC in the Cu. EDAX analysis evident the occurrence of SiC in the matrix. The addition of SiC in Cu improved the hardness and compressive strength (CS). Salt spray corrosion test resulted that, the improved corrosion resistance was obtained for the composite contain 10 wt.% of SiC. The corrosion rate was accomplished for the Cu – 10 wt.% SiC composite as 0.000894535 mm/year. Highest CS was attained for the sample contain 10 wt.% of SiC and highest hardness was observed for the sample contain 15 wt.% of SiC. The strengthening mechanism was discussed with the help of SEM images. The density was decreased and the % porosity was increased for the increasing wt.% of SiC in Cu matrix. The sintered density is higher than the green density for all the samples. From the observed results, it is concluded that produced composites would be suitable for radiator applications.

在这项工作中，铜基复合材料是使用粉末冶金 (PM) 技术由 Cu 和 SiC 粉末合成的。复合材料的组成为 Cu、Cu-5 wt% SiC、Cu-10 wt% SiC 和 Cu-15 wt% SiC，使用 400 kN 液压机制成，并使用马弗炉在 900 °C 下烧结 4 h。对球磨粉末进行扫描电子显微镜 (SEM) 分析，烧结样品显示 SiC 在 Cu 中均匀分散。EDAX 分析表明基体中存在 SiC。在 Cu 中添加 SiC 提高了硬度和抗压强度 (CS)。盐雾腐蚀试验结果表明，含 10 wt.% SiC 的复合材料的耐腐蚀性能得到提高。Cu – 10 wt.% SiC 复合材料的腐蚀速率为 0.000894535 毫米/年。对于含有 10 重量份的样品，获得了最高的 CS。对于含有 15 wt.% SiC 的样品，观察到 SiC 的百分比和最高硬度。借助SEM图像讨论了强化机制。随着 Cu 基体中 SiC 重量百分比的增加，密度降低，孔隙率百分比增加。所有样品的烧结密度都高于生坯密度。从观察结果可以得出结论，生产的复合材料适用于散热器应用。
