摘要
摘要本研究采用电解法制备枝晶铜粉，然后采用化学镀银的方法在其表面镀银。采用热压法制备了不同配比的铜粉和镀银铜粉。结果表明，化学镀银层在样品的颗粒边界处形成了牢固的结合，显著提高了材料的物理力学性能。因此，由镀银枝晶铜颗粒制成的样品的硬度、抗拉强度、电导率和导热系数分别约为98 HB、185 MPa、102 IACS%和402 W mK−1。此外，由完全镀银的铜粉制成的样品的抗氧化性比纯铜高4倍。
Novel advanced copper-silver materials produced from recycled dendritic copper powders using electroless coating and hot pressing
ABSTRACT In this study, copper powders with dendritic morphology were produced by the electrolysis method, and then silver coating was applied to these powders by an electroless coating method. The bulk samples were fabricated by hot pressing method using different ratios of copper and silver-plated copper powders. The results showed that the electroless silver coating layer provided a strong bond at the particle boundaries of the samples, significantly improving the physical and mechanical properties of the materials. Accordingly, the hardness, tensile strength, electrical and thermal conductivity values of the samples produced from silver-plated dendritic copper particles were determined to be approximately 98 HB, 185 MPa, 102 IACS% and 402 W mK−1, respectively. In addition, the oxidation resistance of the sample produced from completely silver-coated copper powders is 4 times higher than that of pure copper.
