目的 针对应用于航天器隔热材料的镍磷空心微点阵,研究向镀层中加入纳米氧化铝颗粒共沉积对镀层导热性能的影响,以及提高其隔热性能的方法。方法 选用模板法和复合化学镀方法制备纳米氧化铝镍磷复合镀层和空心微点阵,采用SEM、EDS对复合镀层的微观组织形貌和表面元素分布进行研究,采用LFA、DSC对复合镀层进行测试,得到其热扩散系数、比热和导热系数。采用一维稳态传热试验和有限元方法得到空心微点阵的等效导热系数,研究镀层导热系数、管长、管径、壁厚以及单胞构型对空心微点阵热传导性能的影响。结果 镍磷镀层中加入纳米氧化铝颗粒后,增加了界面热阻和声子散射,隔热性能提升,导热系数随纳米氧化铝含量的增加而降低。空心微点阵等效导热系数随着镀层导热系数、管径和壁厚的减小而下降,随管长的增大而下降。单胞构型也会影响空心微点阵的孔隙率,进而影响其等效导热系数。结论 该研究为纳米氧化铝增强空心微点阵的隔热性能设计提供了参考。
Abstract
The work aims to study the effect of adding nano-alumina particles to the coating for co-deposition on the thermal conductivity of the coating in nickel-phosphorus hollow micro-lattices used in spacecraft thermal insulation materials, and study the ways to improve its thermal insulation performance. The template method and composite chemical plating method were used to prepare nano-alumina nickel-phosphorus composite coatings and hollow micro-lattices. The microstructure morphology and surface element distribution of the composite coating were studied by SEM and EDS. The thermal diffusion coefficient, specific heat and thermal conductivity of the composite coating were tested by LFA and DSC. The equivalent thermal conductivity of the hollow micro-lattice was obtained by one-dimensional steady-state heat transfer test and finite element method, and the effects of coating thermal conductivity, tube length, tube diameter, wall thickness and unit cell configuration on the thermal conduction performance of hollow micro-lattices were studied. The study showed that the addition of nano-alumina to the nickel-phosphorus coating increased the interfacial thermal resistance and phonon scattering, and improved the thermal insulation performance. The thermal conductivity decreased with the increase of nano-alumina content. The equivalent thermal conductivity of the hollow micro-lattice decreased with the decrease of the thermal conductivity of the coating, the tube diameter and the wall thickness, and decreased with the increase of the tube length. The unit cell configuration also affected the porosity of the hollow micro-lattice and thus affected its equivalent thermal conductivity. This study provides a reference for the design of thermal insulation performance of nano-alumina reinforced hollow micro-lattices.
