Preparation and Exothermic Properties of Ni/Al Multilayer Laminates by Composite Methods
-
摘要: 在纯铝箔上化学镀镍得到微米级厚度的镍层，再将该镀镍铝箔堆垛热压后进行累积叠轧（1~7道次），得到Ni/Al多层板，研究了该多层板的组织结构及放热性能。结果表明：化学镀镍层为非晶态，在热压过程中发生晶化；随着叠轧道次的增加，镍层逐渐发生颈缩和断裂，其碎片镶嵌在铝中，增加了镍和铝的接触面积，从而提高了Ni/Al多层板的放热性能，其能量密度由1道次的520.27 J·g-1增大到7道次的1 203.4 J·g-1，达到理论值的87.15%；不同道次叠轧Ni/Al多层板的起始反应温度均高于475℃，说明该多层板具有良好的室温稳定性。Abstract: A micron-thick nickle layer on pure aluminum foils was obtained by electroless nickel plating. The nickel plated aluminum foils were stacked, hot pressed and accumulative rolling bonded (1-7 passes) to prepare Ni/Al multilayer laminates. The microstructure and exothermic properties of the multilayer laminates were investigated. The results show that the electroless nickel plated layer was amorphous and crystallized during the subsequent hot pressing process. With the increase of the accumulative rolling pass, the nickel layer gradually necked and fractured. The nickel fragments were embedded in the aluminum, increasing the contact area between nickel and aluminum, leading to an increase of the exothermic properties of the Ni/Al multilayer laminates; the energy density of the laminates increased from 520.27 J·g-1 with 1 pass to 1 203.4 J·g-1 with 7 passes, which was 87.15% of the theoretical value. The initial reaction temperatures of the Ni/Al multilayer laminates accumulative rolling bonded with different passes were all higher than 475℃, indicating that the multilayer laminates had good stability at room temperature.
