烧结镍毛细芯的孔参数控制及其对抽吸性能的影响
Control of pore parameters and influence on capillary pumping performance of sintered nickel wicks
摘要
Abstract
Sintered nickel capillary wicks with controlled porosity, pore size distribution and high strength were prepared by salt-leaching pore forming method. The influences of different soluble salts and particle sizes on the capillary pumping performance were investigated. The results showed that the porosity of sintered nickel wicks increased linearly with the amount of soluble salt. When the amount of soluble salt was 40% (mass ratio), the nickel wick porosity reached 73% with high strength. The particle size of soluble salt can influence the pore size distribution of the wicks, but the porosity does not change obviously. The experimental research showed that the capillary pumping performance of the wicks was controlled not only by the porosity, but also by the pore size distribution. With the same porosity, wicks with smaller pore size and more centralized pore size distribution showed more excellent capillary pumping performance.关键词
