摘要

摘要: 以气雾化K418镍基高温合金球形粉末为原料，经过粉末松装烧结制备出高温合金多孔材料。通过对多孔材料微观结构、渗透性能、毛细性能及压缩强度进行表征，研究了原始粉末粒径和烧结温度对多孔吸液芯样品显微结构及性能的影响。结果表明，随烧结温度增加，样品的平均孔径和孔隙率减小；在相同烧结温度下，随着原始粉末粒径增加，样品的平均孔径和孔隙率增大。在烧结温度为1230 ℃，粉末粒径为53～150 μm的条件下，多孔材料样品综合性能最优，渗透率为13.69×10⁻¹⁵ m²，毛细压力为22.1 kPa，压缩强度为86 MPa。

Abstract: The porous superalloy materials were prepared by loose packing sintering using the atomized K418 nickel-based superalloy spherical powders as the raw materials. The microstructure, permeability, capillarity, and compressive strength of the sintered porous material samples were analyzed, and the effects of sintering temperature and original powder particle size on the microstructure and properties of the porous K418 superalloys were investigated. The results show that, the average pore size and porosity decrease with the increase of sintering temperature. At the same sintering temperature, the average pore size and porosity of the sintered samples increase with the increase of the original powder particle size. At the sintering temperature of 1230 ℃ and the powder particle size of 53~150 μm, the comprehensive performance of the porous material samples is the best, the permeability is 13.69×10⁻¹⁵ m², the capillary pressure is 22.1 kPa, and compressive strength is 86 MPa.
